Probes and Biopsy 13-3 
13.1.1  Name and Function of Each Part of the Probe 
The basic structures and corresponding functions of probes are basically the same; the 
following will take probe 3C5A as an example. 
 
No.  Name  Function 
<1>  Probe head  It converts the electrical signal into ultrasound signal, 
making the sound beams focus in the given direction; 
meanwhile, it will receive the ultrasound signal and then 
convert the received signal into electrical signal. The 
lens on the surface is the acoustic lens. Apply 
ultrasound gel on the acoustic lens. 
<2> Needle-guided bracket 
fix tabs and grooves 
Used to mount the needle-guided bracket. 
<3>  Probe cable  Used to transmit electrical signals between the probe 
body and connector. 
<4>  Probe connector  Used to connect the probe to the ultrasonic diagnostic 
system. 
<5>  Lock handle  Used to lock the connector to the ultrasonic diagnostic 
system. 
Tips: 
The probes’ structure marked <2> in the figure above may vary with the matched needle-
guided brackets.
