Probes and Biopsy 13-3
13.1.1 Probe Functions by Part
The basic structures and corresponding functions of probes are basically the same. Take the
following probe as an example.
No. Name Function
<1> Probe head Converts the electrical signal to an ultrasonic signal, focusing
the sound beams in a given direction while it receives the
reflected ultrasonic signal and converts it to an electrical
signal for transmission over the cable. The lens on the surface
is the acoustic lens. Apply ultrasound gel to the acoustic lens
for correct operation.
<2> Needle-guided bracket
fixing tabs and grooves
Provides mounting support for 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 ultrasound diagnostic
system.
<5> Lock handle Locks the connector to the ultrasound diagnostic system.
Tip:
The probes’ structure, marked <2> in the figure above, may vary depending on the corresponding
needle-guided brackets.
