ULTRASONIC DIAGNOSTIC DEVICE, SIGNAL PROCESSING DEVICE AND ANALYSIS PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic device that can quantify attenuation of an echo by a simple configuration, and to provide a signal processing device and an analysis program.SOLUTION: The ultrasonic diagnostic device includes an adjustment part and a processing part. The adjustment part adjusts a received signal that is based on an echo of a supersonic wave transmitted to a subject, by a gain depending on an echo generation position. The processing part corrects the post-adjustment received signal adjusted by the adjustment part depending on the gain and calculates an index value relating to attenuation using the post-correction received signal.SELECTED DRAWING: Figure 1
