General
1.1
Features
C22P Probe is a Convex Array type.
The acoustic output of this probe when connected to ultrasound
diagnostic scanner was measured according to the IEC60601-2-37
standard.
The table of measured acoustic output data is contained in the operation
manual of each ultrasound diagnostic scanner.
This probe is categorized in class IIa according to Directive 93/42/EEC.
According to IEC60601-1 the probe is classified as type BF.
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.
