METHODS, SYSTEMS AND COMPUTER PROGRAM PRODUCTS FOR CONSTRUCTIVE SHEAR WAVE ULTRASOUND IMAGING

摘要

The mechanical parameter of method, system and computer program product determines in sample and provides the displacement of constructive shearing wave using with target area. This method includes generating the first cutter SH waves to excite position in target area absolute atmosphere first, and the second shearing wave is in target area absolute atmosphere secondary excitation position; The target area absolute atmosphere tracing positional for transmitting trace pulse, i.e., in first and Position of Vibrating; Corresponding echo-signal is received for trace pulse tracing positional target area; With the target area for determining at least one mechanical parameter, according to the displacement of at least one structural shearing wave from the first and second shearing waves, while making the tracing positional of tissue movement.
