Probes and Biopsy  13-3 
No.  Name  Function 
<1>  Probe head  Converts the electrical signal into an ultrasonic signal, focusing 
the sound beams in a given direction; meanwhile, it receives 
the reflected ultrasonic signal and converts it into an electrical 
signal for transmission over the cable. The lens on the surface 
is the acoustic lens. Apply ultrasound gel on the acoustic lens 
for correct operation. 
<2>  Needle-guided bracket fix 
tabs and grooves 
Provides mounting support of the needle-guided bracket. 
<3>  Probe cable  Transmits electrical signals between the probe body and 
connector. 
<4>  Probe connector  Connects the probe and cable to the ultrasonic diagnostic 
system. 
Tips: 
The probes’ structure marked <2> in the figure above may vary with the matched needle-guided 
brackets. 
13.1.2  Orientation of the Ultrasound Image and the Probe 
Head 
The orientation of the ultrasound image and the probe are shown as below. The “Mark” side of the 
ultrasound image on the monitor corresponds to the mark side of the probe. Check the orientation 
before the examination (Using a linear probe as an example).
