Mechanical vibrations generating device for magnetic resonance elastography device, has loudspeaker diaphragm connected with tube such that reciprocating movement of diaphragm are transferred to object for generating vibrations in object

摘要

The device has a loudspeaker diaphragm (312) that is connected with a tube (4) via a hinge (311) in such a manner that a periodic reciprocating movement of the diaphragm are transferred to an examination object (1) for generating mechanical vibrations in the examination object. The diaphragm has a sleeve that is centrally arranged for force transmission. The tube is formed in a flexible manner and is filled with a liquid. An independent claim is also included for a method for magnetic resonance elastographic determination of biomechanical characteristics of a tissue.
