Abstract
A system and method for intracorporeal elastography include an intra-luminal vibratory member configured to be positioned within a lumen of an imaging subject and configured to impart mechanical energy into tissue of the lumen. In a preferred embodiment, an external piezoelectric energy source is included and coupled to the vibratory member and configured to cause the vibratory member to longitudinally vibrate, thereby generating shear waves for use with magnetic resonance elastography.
