In order to improve the accuracy of a blood flow image generated in the state in which compression on the tissue of a cross-sectional plane of a subject is changing, disclosed is an ultrasonic diagnosis device provided with an ultrasonic probe (12) which transmits/receives ultrasonic waves to/from the subject, a blood flow image construction unit (30) which generates a blood flow image by Doppler measurement on the basis of a reflection echo signal measured by the ultrasonic probe (12), and an image display unit (36) which displays the blood flow image, the ultrasonic diagnosis device being provided with a measured velocity calculation unit (72) which calculates the measured velocity by Doppler measurement, a tissue movement velocity calculation unit (64) which finds the tissue movement velocity that is the movement velocity of the tissue of the subject, and a blood flow velocity calculation unit (66) which corrects the measured velocity on the basis of the tissue movement velocity to find the blood flow velocity of the subject. The blood flow image construction unit (30) constructs the blood flow image on the basis of the blood flow velocity found by the blood flow velocity calculation unit (66). The blood flow velocity found by the blood flow velocity calculation unit (66) is a velocity independent of the compression technique. |
