The probe contains an electrodynamic actuator (vibrator), an ultrasound transducer and a
measurement trigger button.
24
Probe: A: Electrodynamic actuator. B: Measurement button. C: Indicator light (LED). D:
Ultrasonic transducer. E: Probe lead.
The ultrasound transducer of the probe is a "Type B" applied part, and is the only component
of the FibroScan device in contact with the patient.
Measurement button
As soon as this button is pressed (if sufficient force is placed on the transducer), the
electrodynamic transducer generates a shear wave that painlessly impacts the patient's skin.
At
the same time, the ultrasound transducer performs a series of acquisitions (emission/
reception) to measure the propagation speed of this shear wave. Acquisition lasts less than
one tenth of a second.
Indicators
The indicator lights (LEDs) display a status as follows:
= Lit up blue during FibroScan start-up and when standing by to launch an examination.
= Flashing blue lights for the probe selected when an examination starts.
= Not lit up during an examination when the operator is not applying correct pressure on
the patient's body.
= Lit up blue during an examination when the operator is applying the correct pressure to
the patient's body. It is however strongly recommended that you view the pressure
exerted by looking at the on-screen pressure indicator.
Lead
A B
Probe lead: A: Connection cable. B: Connector.
This 1.5 m lead connects the probe to the FibroScan by means of a multi-pin jack with guide
pin.
四 The probe transducer, the probe jack, and the FibroScan connector are fragile
elements and must be handled with care.
