M+ probe

The standard probe used for adults. (M+ is the third generation version of the M probe.)


A new ergonomy for an optimal performance.


The Fibroscan® M probe*, with optimised ergonomics, makes it possible to take a reliable measurement with easy handling.
It is made up of a single-element ultrasound transducer fixed to the axis of the electro-dynamic transducer. The latter generates a transitory vibration which creates an elastic shear wave. This wave propagates through the skin, the sub-cutaneous tissues, and then the liver. During propagation of the shear wave, the ultrasound transducer carries out a series of echographic acquisitions (emission/reception) in order to measure the propagation velocity of the shear wave. Liver elasticity is calculated from the value of the propagation velocity of this shear wave.


The recommendations for use of the M probe are defined from the morphological data of the patient, in particular the size of his thoracic perimeter (TP). An examination is available, corresponding to the depths of specific measurements which take into account the depth of the liver under the skin and the thoracic perimeter.
