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 Intended 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.
1.3 User 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.
1.4 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.

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

2.3 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.

WARNING: 6. Do not connect any devices other than those specified by
TOSHIBA to the USB connector or other connectors on
the system.
7. Do not connect to the system transducers other than
those specified by TOSHIBA, to prevent accidents such
as fire.
8. Do not use a defective transducer.
9. Do not remove the covers or panels of the system. Doing
so exposes high-voltage parts.
10. 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.
11. 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.
12. 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.
13. Use a separate socket with an appropriate rated capacity
for the supply of power to this system.
14. 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).
