DOPPLER ULTRASOUND DIAGNOSIS DEVICE, DOPPLER ULTRASOUND DIAGNOSIS METHOD, AND PROGRAM

摘要

Acquisition accuracy of motion information and image quality of acoustic property distribution deteriorate if unnecessary reflection waves are present besides reflection waves from an object. A Doppler ultrasound diagnosis device includes: multiple conversion elements (002) to each transmit acoustic waves as to a subject (000), receive reflected waves which have reflected within the subject (000), and convert the received reflected waves into time-sequence reception signals; and a processing unit (007) to acquire information of within the subject (000) by adaptive beam forming processing using a plurality of the reception signals. At least part of the multiple conversion elements (002) perform acoustic wave transmission on a predetermined region within the subject (000) multiple times, thereby outputting multiple time-sequence reception signals based on each of the multiple times of acoustic wave transmission. The adaptive beam forming processing includes integration processing of multiple correlation matrices obtained using the multiple time-sequence reception signals.
