Title:
ULTRASONIC DIAGNOSTIC DEVICE AND ULTRASONIC SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/061560
Kind Code:
A1
Abstract:
This ultrasonic diagnostic device is provided with: a push pulse generating unit 104 that sets a specific site in a subject and causes multiple vibrators 101a to transmit push pulses pp to the specific site; a detection wave pulse generating unit 105 that transmits, multiple times, detection wave pulses pwi which converge outside a region of interest roi in the subject and which pass through the region of interest roi; a displacement detecting unit 109 that generates acoustic line signals for multiple observation points Pij within the region of interest roi in response to the respective detection wave pulses pwi transmitted multiple times, so as to detect a displacement of a tissue within the region of interest roi on the basis of a sequence of acoustic line signal frame data dsi; and an elastic modulus calculating unit 110 that generates a sequence of wave front frame data wfi indicating a wave front position of a shear wave, and calculates, on the basis of the sequence, frame data emk of the elastic modulus or the propagation speed of the shear wave within the region of interest roi.
