ABSTRACT:
A method and a device for noninvasively identifying a region of the tissue having a different elasticity than the surrounding tissue by simultaneously measuring strain and stress patterns in the tissue portion using an ultrasonic imaging system combined with a pressure sensing array. In a particular embodiment, a pressure sensing array made of a sound transparent film inserted between the ultrasonic scanner probe and the tissue measures pressure pattern on the surface of the tissue when the tissue portion is deformed while the scanner detects internal strain pattern. The ultrasonic scanner probe with the attached pressure sensing array serves as a pressure exerting member causing a deformation of the tissue and creating stress and strain in the tissue portion.
