APPARATUS AND METHOD FOR INDICATING MECHANICAL STIFFNESS PROPERTIES OF BODY TISSUE

摘要

Apparatus and method for indicating mechanical stiffness properties of body tissue employing Doppler imaging techniques. Ultrasonic signals that are transmitted to the target not only are reflected for developing images to the target from the reflections, but, by appropriate selection of the intensity of the transmitted signals, the body tissue being investigated is deformed or moved when the transmitted signals impinge on the target. The deformation or movement of the body tissue being investigated is imaged and is representative of the mechanical stiffness of this body tissue.
