■ Although your system has been manufactured in compliance with existing EMI/EMC requirements, use of this system in the presence of an electromagnetic field can cause momentary degradation of the ultrasound image. If this occurs often, MEDISON suggests a review of the environment in which the system is being used, to identify possible sources of radiated emissions. These emissions could be from other electrical devices used within the same room or an adjacent room. Communication devices such as cellular phones and pagers can cause these emissions. The existence of radio, TV, or microwave transmission equipment located nearby can cause emissions. In cases where EMI is causing disturbances, it may be necessary to relocate your system. ■ E lectrostatic discharge (ESD), commonly referred to as a static shock, is a naturally occurring phenomenon. ESD is most prevalent during conditions of low humidity, which can be caused by heating or air conditioning. During low humidity conditions, electrical charges naturally build up on individuals and can create static shocks. An ESD condition occurs when an individual with an electrical energy build-up comes in contact with objects such as metal doorknobs, file cabinets, computer equipment, and even other individuals. The static shock or ESD is a discharge of the electrical energy build-up from a charged individual to a lesser or non-charged individual or object. The level of electrical energy discharged from a system user or patient to the ultrasound system can be significant enough to cause damage to the system or probes. The following precautions can help to reduce ESD: anti-static spray on carpets; anti-static spray on linoleum; anti-static mats; or a ground wire connection between the system and the patient table or bed.

Sheaths are recommended for clinical application of an invasive nature, including intraoperative, transrectal, transvaginal, and biopsy procedures. MEDISON does not supply sheaths so that you should purchase appropriate ones on your own. Some sheaths contain natural rubber latex and talc, which can cause allergic reactions in some individuals, Refer to the FDA Medical Alert, March 29, 1991, reprinted here.
Warning
In neurosurgical applications, sterilized probes should be used with sterile gel and a sterile pyrogen-free sheath. If the sterile sheath becomes compromised during neurosurgical applications involving a patient with Creutzfeldt-Jakob disease, the probe cannot be sterilized with any sterilization method. Sheaths are disposable and must not be reused. If an installed sheath is cut or contaminated prior to use, the probe should be cleaned and disinfected, and a new sterile sheath installed.
ALARA Education Program The guidance for the use of diagnostic ultrasound is defined by the “as low as reasonably achievable” (ALARA) principle. The decision as to what is reasonable has been left to the judgment and insight of qualified personnel. No set of rules can be formulated that would be sufficiently complete to dictate the correct response to every circumstances. By keeping ultrasound exposure as low as possible, while obtaining diagnostic images, users can minimize ultrasonic bioeffects. Since the threshold for diagnostic ultrasound bioeffects is undetermined, it is the sonographer’s responsibility to control total energy transmitted into the patient. The sonographer must reconcile exposure time with diagnostic image quality. To ensure diagnostic image quality and limit exposure time, an ultrasound system provides controls that can be manipulated during the exam to optimize the results of the exam. The ability of the user to abide by the ALARA principle is important. Advances in diagnostic ultrasound not only in the technology but also in the applications of that technology, have resulted in the need for more and better information to guide the user. The output indices are designed to provide that important information There are a number of variables, which affect the way in which the output display indices can be used to implement the ALARA principle. These variables include values, body size, location of the bone relative to the focal point, attenuation in the body, and ultrasound exposure time. Exposure time is an especially useful variable, because the user controls it. The ability to limit the index values over time supports the ALARA principle.

Applying ALARA The system-imaging mode used depends upon the information needed. B-mode and M-mode imaging provide anatomical information, while Doppler, Power, and Color imaging provide information about blood flow. A scanned mode, like B-mode, Power, or Color, disperses or scatters the ultrasonic energy over an area, while an unscanned mode, like M-mode or Doppler, concentrates ultrasonic energy. Understanding the nature of the imaging mode being used allows the sonographer to apply the ALARA principle with informed judgment. Additionally, the probe frequency, system set-up values, scanning techniques, and operator experience allow the sonographer to meet the definition of the ALARA principle. The decision as to the amount of acoustic output is, in the final analysis, up to the system operator. This decision must be based on the following factors: type of patient, type of exam, patient history, ease or difficulty of obtaining diagnostically useful information, and the potential localized heating of the patient due to probe surface temperatures. Prudent use of the system occurs when patient exposure is limited to the lowest index reading for the shortest amount of time necessary to achieve acceptable diagnostic results. Although a high index reading does not mean that a bioeffect is actually occurring, a high index reading should be taken seriously. Every effort should be made to reduce the possible effects of a high index reading. Limiting exposure time is an effective way to accomplish this goal. There are several system controls that the operator can use to adjust the image quality and limit the acoustic intensity. These controls are related to the techniques that an operator might use to implement ALARA. These controls can be divided into three categories: direct, indirect, and receiver control.
Direct Controls Application selection and the output intensity control directly affect acoustic intensity. There are different ranges of allowable intensity or output based on your selection. Selecting the correct range of acoustic intensity for the application is one of the first things that occur in any exam. For example, peripheral vascular intensity levels are not recommended for fetal exams. Some systems automatically select the proper range for a particular application, while others require manual selection. Ultimately, the user has the responsibility for proper clinical use. The Medison system provides both automatic or default and manual or user-selectable settings. Output has direct impact on acoustic intensity. Once the application has been established, the output control can be used to increase or decrease the intensity output. The output control allows you to select intensity levels less than the established maximum. Prudent use dictates that you select the lowest output intensity that is consistent with good image quality.

SONOACE 8000SE
Safety
Chapter 2
2-12
Indirect Controls The indirect controls are those that have an indirect effect on acoustic intensity. These controls affect imaging mode, pulse repetition frequency, focus depth, pulse length, and probe selection. The choice of imaging mode determines the nature of the ultrasound beam. B-mode is a scanning mode, Doppler is a stationary or unscanned mode. A stationary ultrasound beam concentrates energy in a single location. A moving or scanned ultrasound beam disperses the energy over an area and the beam is concentrated on the same area of a fraction of the time as that of an unscanned mode. Pulse repetition frequency or rate refers to the number of ultrasound bursts of energy over a specific period of time. The higher the pulse repetition frequency, the more pulse of energy in a period of time. Several controls affect pulse repetition frequency: focal depth, display depth, sample volume depth, color sensitivity, number of focal zones, and sector width controls. Focus of the ultrasound beam affects the image resolution. To maintain or increase resolution at a different focus requires a variation in output over the focal zone. This variation of output is a function of system optimization. Different exams require different focal depths. Setting the focus at the proper depth improves the resolution of the structure of interest. Pulse length is the time during which the ultrasonic burst is turned on. The longer the pulse, the greater the time-average intensity value. The greater the time-average intensity, the greater the likelihood of temperature increase and cavitations. Pulse length or burst length or pulse duration is the output pulse duration in pulsed Doppler. Increasing the Doppler sample volume increases the pulse length. Probe selection indirectly affects intensity. Tissue attenuation changes with frequency. The higher the probe operating frequency, the greater the attenuation of the ultrasonic energy. A higher probe operating frequency requires more output intensity to scan at a deeper depth. To scan deeper at the same output intensity, a lower probe frequency is required. Using more gain and output beyond a point, without corresponding increases in image quality, can mean that a lower frequency probe is needed.
Receiver Controls Receiver controls are used by the operator to improve image quality. These controls have no effect on output. Receiver controls only affect how the ultrasound echo is received. These controls include gain, TGC, dynamic range, and image processing. The important thing to remember, relative to output, is that receiver controls should be optimized before output is increased. For example; before increasing output, optimize gain to improve image quality.

Additional Considerations Ensure that scanning time is kept to a minimum, and ensure that only medically required scanning is performed. Never compromise quality by rushing through an exam. A poor exam require a follow-up, which ultimately increase time. Diagnostic ultrasound is an important tool in medicine, and, like any tool, it should be used efficiently and effectively.
Output Display Features The system output display comprises two basic indices: a mechanical index and a thermal index. The thermal index further consists of the following indices: soft tissue (TIs) and bone (TIb). One of these three thermal indices will be displayed at all times. Which one depends upon the system preset or user choice, depending upon the application at hand. The mechanical index is continuously displayed over the range of 0.0 to 1.9, in increments of 0.1 The thermal index consists of the three indices, and only one of these is displayed at any one time. Each probe application has a default selection that is appropriate for that combination. The TIb or TIs is continuously displayed over the range of 0.0 to maximum output, based on the probe and application, in increments of 0.1. The application-specific nature of the default setting is also an important factor of index behavior. A default setting is a system control state which is preset by the manufacturer or the operator. The system has default index settings for the probe application. The default settings are invoked automatically by the ultrasound system when power is turned on, new patient data is entered into the system database, or a change in application takes place. The decision to display one or the other of the three thermal indices should be based on the following criteria: Appropriate index for the application: TIs is used for imaging soft tissue; and TIb for a focus at or near bone. Mitigating factors that might create artificially high or low thermal index readings: location of fluid or bone, or blood flow. For example, is there a highly attenuating tissue path so that the actual potential for local zone heating is less than the thermal index displays. Probe modes versus unscanned modes of operation affect the thermal index. For scanned modes, heating tends to be near the surface; for unscanned modes, the potential for heating tends to be deeper in the focal zone. Always limit ultrasound exposure time. Do not rush the exam. Ensure that the indices are kept to a minimum and that exposure time is limited without compromising diagnostic sensitivity.
Mechanical Index (MI) Display Mechanical bioeffects are threshold phenomena that occur when a certain level of output is exceeded. The threshold level varies, however, with the type of tissue. The potential for mechanical bioeffects varies with peak pressure and ultrasound frequency. The MI accounts for these two factors. The higher the MI value, the greater the likelihood of mechanical bioeffects occurring. There is no specific MI value that means that a mechanical effect is actually occurring. The MI should be used as a guide for implementing the ALARA principle.

hermal Index (TI) Display The TI informs the user about the potential for temperature increase existing at the surface f the body, within the body tissue, or at the point of focus of the ultrasound beam on bone. he TI is an estimate of temperature increase in body tissue with specific properties. he actual amount of any temperature rise is influenced by factors such as tissue type, ascularity, mode of operation and others. The TI should be used as a guide for mplementing the ALARA principle. he bone thermal index (TIb) informs the user about potential heating at or near the focus after the ltrasound beam has passed through soft tissue or fluid, for example, at or near second or third imester fetal bone. he cranial bone thermal index (TIc) informs the user about the potential heating of bone at or near he surface, for example, cranial bone. he soft tissue thermal index (TIs) informs the user about the potential for heating within soft omogeneous tissue. ou can select either TIs or TIb using the TIs/TIb selection on the Miscellaneous system setups.

Control Effrcts Control affecting the indices As various system controls are adjusted, the TI and MI values may change. This will be most apparent as the POWER control is adjusted; however, other system controls will affect the onscreen output values.
POWER Power controls the system acoustic output. Two real-time output values are on the screen: a TI and a MI. They change as the system responds to POWER adjustments. In combined modes, such as simultaneous Color, B-mode and pulsed Doppler, the individual modes each add to the total TI. One mode will be the dominant contributor to this total. The displayed MI will be from the mode with the largest peak pressure.
B mode Controls B-mode size Narrowing the sector angle may increase frame rate. This action will increase the TI. Pulser voltage may be automatically adjusted down with software controls to keep the TI below the system maximums. A decrease in pulser voltage will decrease MI.
ZOOM Increasing the zoom magnification may increase frame rate. This action will increase the TI. The number of focal zones may also increase automatically to improve resolution. This action may change MI since the peak intensity can occur at a different depth.
Persistence A lower persistence will decrease the TI. Pulser voltage may be automatically increased. An increase in pulser voltage will increase MI.
Focal no. More focal zones may change both the TI and MI by changing frame rate or focal depth automatically. Lower frame rates decrease the TI. MI displayed will correspond to the zone will the largest peak intensity.
FOCUS Changing the focal depth will change MI. Generally, higher MI value will occur when the focal depth is near the natural focus of the transducer.

Color and Cintrols Color Sensitivity Increasing the color sensitivity may increase the TI. More time is spent scanning the color image. Color pulses are the dominant pulse type in this mode.
Color Sector Width Narrower color sector width will increase color frame rate and the TI will increase. The system may automatically decrease pulser voltage to stay below the system maximum. A decrease in pulser voltage will decrease the MI. If pulsed Doppler is also enabled then pulsed Doppler will remain the dominant mode and the TI change will be small.
Color Sector Depth Deeper color sector depth may automatically decrease color frame rate or select a new color focal zone or color pulse length. The TI will change due to the combination of these effects. Generally, the TI will decrease with increased color sector depth. MI will correspond to the peak intensity of the dominant pulse type, which is a color pulse. However, if pulsed Doppler is also enabled then pulsed Doppler will remain the dominant mode and the TI change will be small.
SCALE Using the SCALE control to increase the color velocity range may increase the TI. The system may automatically adjust pulser voltage to stay below the system maximums. A decrease in pulser voltage will also decrease MI.
SEC WIDTH A narrower B-mode sector width in Color imaging will increase color frame rate. The TI will increase. MI will not change. If pulsed Doppler is also enabled, then pulsed Doppler will remain the dominant mode and the TI change will be small.
M-mode and Doppler Controls Speed M-mode and Doppler sweep speed adjustments will not affect the MI. When M-mode sweep speed changes, TI changes.
Simultaneous and Update Methods Use of combination modes affects both the TI and MI through the combination of pulse types. During simultaneous mode, the TI is additive. During auto-update and duplex, the TI will display the dominant pulse type. The displayed MI will be from the mode with the largest peak pressure.
Sample Volume Depth When Doppler sample volume depth is increased the Doppler PRF may automatically decrease. A decrease in PRF will decrease the TI. The system may also automatically decrease the pulser voltage to remain below the system maximum. A decrease in pulser voltage will decrease MI.

DOPPLER, M-MODE, and COLOR Imaging Controls When a new imaging mode is selected, both the TI and MI may change to default settings. Each mode has a corresponding pulse repetition frequency and maximum intensity point. In combined or simultaneous modes, the TI is the sum of the contribution from the modes enabled and MI is the MI for the focal zone and mode with the largest derated intensity. The system will return to the previously selected state if a mode is turned off and then reselected.
Probe Each probe model available has unique specifications for contact area, beam shape, and center frequency. Defaults are initialized when you select a probe. MEDISON factory defaults vary with probe, application, and selected mode. Defaults have been chosen below the FDA limits for intended use.
DEPTH An increase in B-mode depth will automatically decrease the B-mode frame rate. This would decrease the TI. The system may also automatically choose a deeper B-mode focal depth. A change of focal depth may change the MI. The MI displayed is that of the zone with the largest peak intensity.
Application Acoustic output defaults are set when you select an application. Medison factory defaults vary with probe, application, and mode. Defaults have been chosen below the FDA limits for intended use.
Acoustic Output and Measurement Since the initial use of diagnostic ultrasound, the possible human biological effects (bioeffects) from ultrasound exposure have been studied by various scientific and medical institutions. In October 1987, the American Institute of Ultrasound in Medicine(AIUM) ratified a report prepared by its Bioeffects Committee(Bioeffects Considerations for the Safety of Diagnostic Ultrasound, J Ultrasound Med., Sept. 1988: Vol.7, No.9 Supplement), sometimes referred to as the Stowe Report, which reviewed available data on possible effects of ultrasound exposure. Another report “Bioeffects and Safety of Diagnostic Ultrasound,” dated January 28, 1993 provides more current information. The acoustic output for this system has been measured and calculated in accordance with the December 1985 “510(K) Guided for Measuring and Reporting Acoustic Output of Diagnostic Ultrasound Medical Devices,” except that the hydrophone meets the requirements of “Acoustic Output Measurement Standard for Diagnostic Ultrasound Equipment” (NEMA UD 2-1992)

Caution
Excessive bending or twisting of cables on patient-applied parts may cause failure or intermittent operation of the system. Improper cleaning or sterilization of a patient-applied part may cause permanent damage. Do not submerge the cables of patient-applied parts in solution. The cables are not liquid-tight beyond the applied part/cable or cable/connector interfaces. Do not use solvents such as thinner or benzene, or abrasive cleaners on the system, probes or peripheral devices. The system has been designed for 100-120Vac and 200-240Vac; you should select the input voltage of monitor, printer and VCR. Prior to connecting an OEM power cord, verify that the voltage indicated on the power cord matches the voltage rating of the OEM device. An isolation transformer protects the system from power surges. The isolation transformer continues to operate when the system is in standby. In general, only the area of the probe acoustic window is watertight (IPX7). Except where specified in specific cleaning instructions, do not immerse the remainder of a probe in any liquid. For optimal performance, your MEDISON ultrasound system should be connected to a circuit dedicated solely for the ultrasound system. Use only the foot switch, which Medison supplies, and check the Medison logo symbol on it.

Probe Management Warning
Always use protective eyewear and gloves when cleaning and disinfecting probes and biopsy guide adapters.
Probes must be cleaned after each use. Cleaning the probe is an essential step prior to effective disinfection or sterilization. Be sure to follow the manufacturer’s instructions when using disinfectants.
Caution
Do not allow sharp objects, such as scalpels or cauterizing knives, to touch probes or cables. When handling a probe, do not bump the probe on hard surfaces.
Probe is the most important factor in image quality. Optimal imaging cannot be attained without the correct probe. The system is optimized for use based on your probe selection.
Caution
Do not use a surgeon’s brush when cleaning probes. The use of even soft brushes can damage the probe. During cleaning, disinfection, and strilization, orient the parts of the probe that must remain dry higher than the wetted parts until all parts are dry. This will help keep liquid from entering non-liquid-tight areas of the probe.
Disconnect the probe from the system. Remove any sheaths, biopsy guide adapters, or biopsy needle guides(biopsy guide adapters are reusable portion of the biopsy guide and can be sterilized.) Discard sheaths(sheaths are single-use item) Use a soft cloth lightly dampened in a mild soap or compatible cleaning solution to remove any particulate matter or body fluids that remain on the probe or cable. To remove remaining particulates, rinse with water up to the immersion point. Wipe with a dry cloth; or wipe with a water-dampened cloth to remove soap residue, and then wipe with a dry cloth.

If a pre-mixed solution is used, be sure to observe the solution expiration date.
Warning
The type of tissue it will contact during use dictates the level of disinfection required for a device. Ensure that the solution strength and duration of contact are appropriate for disinfection or sterilization. Be sure to follow the manufacturer’s instructions. In neurosurgical application, sterilized probes should be used with a pyrogen-free sheath.
Using a non-recommended disinfection solution, incorrect solution strength, or immersing a probe deeper or for a period longer than recommended can damage or discolor the probe and will void the probe warranty.
Caution
Do not immerse probes longer than one hour, unless they are sterilizable. Probes may be damaged by longer immersion times. Sterilize probes using only liquid solutions. Using autoclave, gas(EtO), or other non-MEDISON-approved methods will damage your probe and void your warranty.

Performance Tests Wiring and Cautions Warnings Never open the safety cover of this equipment. Internal parts of the equipment are supplied with high voltage electricity. All internal repairs and part replacements must be carried out only by the Medison Customer Service Department. Electrostatic Discharge (ESD), generally known to be caused by shocks of static charges, can occur in natural conditions. ESD occurs most commonly in dry conditions, such as during operation of heaters or air conditioners. ESD also occurs when contacting metal door handles, file cabinets, computer parts or even another person. Static charges and ESD are produced when electrically charged materials release electricity to charge less charged materials. It is possible that the static charges released by the system user or the patient may damage the ultrasonographic system or the probe. Always observe the following guidelines to prevent damages by ESD: 1. Spray anti-static charge spray over the carpet or the linoleum. 2. Use anti-static charge mats. 3. Ground the system and the patient’s table or bed.

Probe Select Assembly (PSA) Figure 7-4 is a simple block diagram of the PSA PCB. The PSA contains three probe connectors. When a probe is selected in the user menu, a connector of the probe become select. The PSA acts as a gateway that connects the probes and the system. It reads the probe ID upon booting and sends the data to the CW PCB. Then the CW PCB decodes the data and transmits it to the CPU.

Beamformer Figure 6-7 is a functional block diagram of the Beamformer PCB. The Beamformer consists of 1 PCB. It generates transmission pulses in order to operate the probe elements. The received echo signals are sent through the filter for eliminating noise. Then the signals are amplified to specific levels by the PREAMP and are converted to digital signals for digital beamforming. The delay them of time digital signals are controlled by the FIFO and then are summed together by the BFIC. This process is called beamforming. In addition, the Beamformer also performs Dynamic Apodization, Multi Beam Receiving, TGC and other functions for improving the image quality.

Digital Scan Converter (DSC) The Digital Scan Converter PCB consists of three main parts: a Digital Signal Processing (DSP) Part, a Digital Scan Converter (DSC) Part, and a Video Manager (VM) Part.
DSP Part The DSP Part consists of a 2D mode part, a Spectral Doppler Part, and a Color Doppler Part. The 2D mode part receives the beamformed output signals, generates B/W signal (2D image) data and sends it to the DSC Part. The Spectral doppler mode part separates the RF signals received for Doppler direction separation into I (Inphase) signals and Q (Quadrature) signals. Then it uses the clutter filter to remove the clutter noise in which is a kind o wall noise from vein wall out of the signals. The signals with wall noise removed are sent to the PCC Board for the Doppler Sound process, and they are sent to the FFT circuit, where the basic Doppler elements Power, Velocity, and Variance are analyzed. The Color Doppler mode part receives the I signals and Q signals, removes the wall noise and adds colors by using Color Flow Mapping.
DSC Part The DSC Part consists of the image filter circuit (which improves the image quality), the frame memory part (which writes the scan line data and displays the monitor on the H-sync), Zoom, and FreeHand 3D Path. The DSC Part combines into one screen the information from the 2D / Spectral Doppler / Color Doppler modes which are generated through different paths.
VM Part The VM Part converts the digital data into RGC signals for displaying on the monitor and converts the digital signals into analog signals. It also combines the menu information from the PC and the image information from the system together for displaying on the screen. It generates various video output signals in order to support other external devices.

PC Carrier (PCC) PCB The PC Carrier (PCC) PCB consists of three main parts: a PC Part, a VM Part, and a Doppler Sound Part.
PC Part Components and Functions The PC Part consists of the PC Module, which is the central part of the system, and the PC Interface which controls the data and signals of the PC and the System. The PC Part controls the entire PCC PCB and manages the data input and output.
Video Manager Part Components and Functions The Video Manager Part is the last device that the signals go through before being sent as display signals. The Video Manager Part consists of the DAC (which converts digital signals into analog signals), the Encoder (which converts digital signals into VCR signals), and the Decoder (which allows the external video signals to be displayed on the system).
Audio Sound Part Components and Functions The Audio Sound Part is the last device that processes Doppler Sound for the Spectral Doppler. The Audio Sound Part consists of the D/A converter (which converts digital signals into analog signals), a filter (LPF) (which removes the noise from Doppler signals), and the Power Amp (which amplifies the audio to sufficient output levels). This part also includes a microphone that can be used for adding audio information when recording the ultrasonographic scanner video.

Terms CAUTION: Message containing caution information to protect the product.
Digital Imaging and Communication in Medicine Electromagnetic Interference (EMI): A standard for network communication. This system provides devices and network communication methods that comply with the version 3.0 regulation standard for external signals and noise that may degrade the performance of the electronic devices.
I-RGB: Interlaced, red, green, and blue video signals. This system includes the rear panel connector to support video devices that use this type of video signals.
Interlaced: Interlaced is the current television scanning standard. One full screen frame is generally made of 525 horizontal lines. The interlaced method scans 262.5 fields, repeatedly deflecting the scanning lines vertically. In other words, one full screen frame is made by two instances of scanning. As a result, the screen may flicker at 30 frames per second, but the same screen will not flicker at 60 frames per second.
National Television Standards Committee Non-Interlaced: US broadcasting standard video signal (scanning at 525 line, 60Hz).
QWERTY Keyboard: Keyboard with the top left keys laid out in the order of QWERTY. It is to the standard computer keyboard type.
Phased Alternating Line: It is the European video standard signal scanning: the 625 Line and 50Hz Composite Video signal format.
WARNING: Message containing caution information to protect the user and patient from possible risks and dangers.
