Take 3.5MHz convex array probe for example:
Figure: Parts name of 3.5MHz convex array probe
Name
Function
(1) Acoustic lens
To convert electric signal to ultrasonic signal based on principle of
converse piezoelectric effect. The ultrasonic signal, after entering the
human body, is reflected as echo wave and converted to electric signal
again. The acoustic lens is on the probe surface. Supply ultrasonic
coupling gel to the acoustic lens surface when performing ultrasonic
diagnosis.
(2) Cable
To connect the probe to the probe connector.
(3) Probe connector
To connect the probe to ultrasonic diagnostic instrument.
