DEVICE FOR EXAMINING VISCOELASTICITY OF A LIVING OF ARTIFICIAL TISSUE

摘要

A probe for examining viscoelasticity and anisotropy of an area of an external layer of a living or artificial tissue, comprises an assembly (34) including at least one group of piezoelectric spaced-apart transducers (78, 80, 82), each having a surface contact making edge, wherein one of said transducers operates as a transmitter and at least one other transducer operates as a receiver, and wherein said assembly is movable both axially, as well as angulary; means for effecting the controlled axial movement (22, 24) of said assembly; means for controlling the contact pressure (24) to be exerted by the transducers on the surface of an area of a tissue to be examined, and means for effecting angular movement of said assembly (18, 20) at a selected axial displacement.
