General
The EUP-C532 is a Convex Array Probe.
The acoustic output of the EUP-C532 was measured according to
the IEC60601-2-37 standard and the measurement was conducted by
operating with the Hitachi ultrasound diagnostic scanner.
The measured acoustic output is listed in the instruction manual
of the Hitachi ultrasound diagnostic scanner.
The EUP-C532 is categorized in class IIa according to Directive
93/42/EEC and classified as type BF according to IEC60601-1.
1.2
Principles of operation
This probe and the ultrasound diagnostic scanner enable image
diagnosis using ultrasonic waves. This system operates under the
principles described below.
1)
When an electric pulse signal is applied from the transmitter
to the transducer of the probe, the transducer converts
electric signals into mechanical vibration energy for
emitting pulse-shaped ultrasonic waves into the body part,
liquid or other medium contacting the transducer.
2)
The emitted ultrasonic waves are reflected by boundaries with
different acoustic characteristics (acoustic impedance)
within the body.
3)
The transducer is also used to receive reflected ultrasonic
waves. The transducer vibrates mechanically due to the
received ultrasonic waves and converts mechanical
vibrations into electric energy. Electric signals are
converted to shades of brightness by brightness modulation
to obtain an image.
