Probes and Biopsy 13-5
<1> Transducer 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>
bracket fix tabs and
grooves
Used to mount the needle-guided bracket.
<3> Transducer cable
Used to transmit electrical signals between the transducer
body and connector.
<4> Transducer connector
Used to connect the transducer to the ultrasonic diagnostic
system.
<5>
Lock handle
This locks the connector to the ultrasonic diagnostic
system.
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
Transducer Head
The orientation of the ultrasound image and the transducer are shown below. The “MARK”
side of the ultrasound image on the monitor corresponds to the mark side of the transducer.
Check the orientation before the examination (take linear probe as an example).
