1. Intended Use 1.1

Intended Medical Use (1) The intended use of this system is to visualize structures, characteristics, and dynamic processes within the human body using ultrasound and to provide image information for diagnosis. (2) This system provides high-quality ultrasound images in all its modes: 4D mode, 2D mode, M mode, CDI (Color Doppler Imaging) mode (blood-flow imaging), and Doppler mode (blood-flow spectrum). (3) This system is a general-purpose diagnostic ultrasound imaging system that conforms to the standard for Real Time Display of Thermal and Mechanical Output Indices on Diagnostic Ultrasound Equipment (American Institute of Ultrasound in Medicine (AIUM), 1992). Note that transducers have their own characteristic applications. For the transducers that can be used with this system and their applications, refer to subsection 5.6 "List of Available Transducers".

1.2

Operating Principles This system transmits ultrasound signals into the human body from a transducer and receives the reflected echoes from the human body using the same transducer. It then processes the received signals and displays them as images on a display screen (LCD monitor). Gating signals are sent from the scan control circuit through the transmission delay circuit and are input to the reception circuit. The reception circuit then generates the transmission signals (electrical pulses) according to the gating signals. These electrical pulses are applied to piezoelectric elements that convert the electrical signals into mechanical vibrations in the transducer. These mechanical vibrations, which are ultrasound signals, are then transmitted into the human body. This system supports convex, sector, linear, and some other scanning techniques. When the ultrasound signals transmitted into the human body encounter a substance with different acoustic characteristics, they are reflected and return to the transducer as echoes. Based on the time required for the ultrasound signals to return to the transducer, the distance between the transducer surface and the reflecting substance can be determined. In 2D (B) mode imaging, the echo amplitudes are represented as brightness changes on the image display screen. Since the ultrasound beam attenuates in tissue, the degree of amplification required generally increases as depth increases. Regions of high reflection are displayed as brighter, while regions of low reflection appear darker. An M-mode image (cross-sectional image) can be displayed together with a 2D-mode image on the same screen through time-sharing control, allowing the user to perform M-mode diagnosis while observing a 2D-mode image.

No. 2B771-004EN*K 1-1

In color Doppler imaging, phase detection is performed in a receive signal processing circuit to obtain I and Q signals. These signals undergo frequency analysis with the correlational method in a color Doppler imaging circuit to produce the mean velocity, variance, and power information of the blood flow. These information items are assigned color signals and represented as real-time two-dimensional color Doppler images. In Doppler imaging, the signals output from the receive signal processing board are frequency-analyzed by fast Fourier transform (FFT) in a Doppler circuit to produce velocity and power information. A Doppler image is then displayed, plotting velocity on the vertical axis, time on the horizontal axis, and representing power as brightness. This system supports basic measurements including distance, time, angle, and trace, as well as combinations of some basic measurements. In addition, calculations based on the measurement values can be performed for each region (circulatory organ, OB, etc.) using widely accepted expressions. The calculation results can be displayed in values, tables, or graphs.

2.3

Ensuring the Safety of Patients and Operators Observe the following safety precautions to ensure the safety of patients and operators.

DANGER:

This system must be used only when the potential benefits to the patient are judged outweigh the possible risk to the patient.

WARNING: 1. Do not use damaged or defective transducers. Doing so may result in injury to the patient. 2. Take special precautions when examining a patient with high temperature. A high patient temperature may slow down cooling of the transducer surface, which may result in a burn injury to the patient. If the surface temperature of the transducer becomes abnormally high, stop using the transducer and contact your TOSHIBA service representative. 3. This device is contraindicated for ophthalmic use or any application that causes the acoustic beam to pass through the eye. 4. Do not look inside the DVD/CD unit. The emitted laser beam is hazardous to the eyes and other parts of the body. 5. Prolonged and repeated use of keyboards can result in hand or arm nerve disorders in some individuals. Observe the local institutional work safety/health regulations on keyboard use. 6. Do not use the Fusion function (option) for patients who use electronic life-support devices (for example, a cardiac pacemaker or defibrillator). The magnetic field generated in Fusion mode may affect such devices.

CAUTION: 1. Do not use the transducer on the same region of the patient for a prolonged period. Low temperature burns may occur. Use the transducer for the minimum period of time that is required for diagnosis. Though the transducer surface temperature may exceed the patient's body temperature under some ambient conditions and usage modes, the use of the transducer for normal ultrasound diagnosis is unlikely to cause low temperature burns. 2. Do not sit on the system. Doing so may result in the system moving unexpectedly, causing you to lose your balance and fall. 3. When this system is used to examine an elderly patient or an infant, an attendant should be present if required.

No. 2B771-004EN*K 2-2

2.4

Preventing Electric Shocks, Fires, and Power Supply Interruptions Observe the following safety precautions to prevent electric shocks, fires, and power supply interruptions.

DANGER:

Never use flammable or explosive gases near this system. Also do not use the system with oxygen or in an oxygenenriched atmosphere. Doing so may result in an explosion (the system is not explosion-proof).

WARNING: 1. Follow the instructions below regarding the power cable and plug.  Insert the power plug only into an AC 100-V (50-Hz/ 60-Hz), 3-pin (with grounding) medical electrical outlet.  Do not connect the power cable to a 2-pin outlet using an adapter.  Do not forcibly bend the cable.  Do not modify the power cable or plug.  Do not damage the power cable or plug.  Do not pull the power cable to disconnect the plug from the outlet. 2. If an abnormal smell or noise, or smoke occurs, immediately turn the main power switch on the power panel OFF and disconnect the plug from the power outlet. Continuing to use the system with such an abnormality may result in a fire etc. When using the system, ensure that there is enough space for access to the main power switch. 3. Do not allow this system or other equipment to come into contact with the patient. If this system or other equipment is defective, the patient may receive an electric shock. 4. Do not connect any devices other than those specified by TOSHIBA to the USB connector or other connectors on the system. 5. Do not connect to the system transducers other than those specified by TOSHIBA, to prevent accidents such as fire. 6. Do not use a defective transducer. 7. Do not remove the covers or panels of the system. Doing so exposes high-voltage parts. 8. When in the patient environment, the operator must not touch any exposed connectors. In addition, if the system covers have been removed for some reason, the operator must be extremely careful not to touch any part where the voltage exceeds 25 VAC or 60 VDC and the patient at the same time. Doing so may result in an electric shock.

No. 2B771-004EN*K 2-3

WARNING: 9. Connect the equipotential terminal (

) of this system to

the equipotential bus of the facility using an equipotential conductor. When this system is used close to a device that is applied directly to the patient heart (such as in a cardiac catheterization room, CCU, or ICU), voltage equalization with the device is required to prevent an electric shock to the patient. 10. A functional ground terminal ( ) is used to connect a functional grounding wire between systems or between the system and the ground for functional purposes of the system (for example, to eliminate potential differences in the signal level between systems or to eliminate potential differences between the system and the ground). Do not use the functional ground terminal for protective grounding. Also, do not connect the functional ground terminal to a gas pipe or water pipe. Doing so may result in the failure of functional grounding or in a gas explosion. 11. Use a separate socket with an appropriate rated capacity for the supply of power to this system. 12. Do not connect this system to an outlet that shares a circuit breaker (or fuse) with an outlet to which a device such as a life-support system is connected. If this system malfunctions and generates an overcurrent, or if there is a current surge when the power is turned ON, the circuit breaker may trip (or the fuse may blow). 13. Do not connect the diagnostic ultrasound system to the same power outlet as another device. Doing so may cause the circuit breaker of the facility to trip, fuses to blow, or a fire or electric shock to occur. 14. Remove the ECG electrodes from the patient before using devices such as electric scalpels, high-frequency therapy equipment, electrostimulators, or electric defibrillators. In addition, when using such devices, do not let ultrasound transducers, PCG microphones, or pulse wave sensors to come into contact with the patient. Doing so may result in the patient receiving a burn injury or an electric shock.

CAUTION: 1. To prevent electric shock, do not connect peripheral units (such as a video printer or video recording unit) to an external outlet. Peripheral units should be connected inside the system. For the connection procedures, contact your TOSHIBA service representative. 2. If any abnormality of the system is found as a result of inspection, stop using the system and contact your TOSHIBA service representative for repair. 3. Do not spill or spray liquids such as water onto the system or peripheral units.
