1. Intended Use

1.1Intended 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».

1.2Intended Patient Information

Age, health condition: Not specified

However, do not use this system if it is judged that the patient will be exposed to hazard due to the patient’s own condition.

1.3User Profile

Only physicians or legally qualified persons who have received appropriate training

Before using this system, it must be ensured that the user has received sufficient training.

1.4Operating 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.

No. 2B771-004EN*M

1-1

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.

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.

2.3Ensuring 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.
