Ultrasonic diagnostic apparatus, controller of ultrasonic diagnostic apparatus and control method of ultrasonic diagnostic apparatus

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic device capable of highly accurately detecting a lumen tunica intima boundary and a tunica media-tunica externa boundary, a controller of the ultrasonic diagnostic device and a control method of the ultrasonic diagnostic device.SOLUTION: An ultrasonic diagnostic device includes: an ROI setting part 6 which sets an area of interest on a front wall of a carotid artery; a first boundary candidate detection part 7 which generates signal intensity distribution in a depth direction of a reception signal in the area of interest, and detects a first tunica media-tunica externa boundary candidate position and a first lumen tunica intima boundary candidate position in the signal intensity distribution as a first blood vessel boundary candidate position; a second boundary candidate detection part 8 which detects a second tunica media-tunica externa boundary candidate position and a second lumen tunica intima boundary candidate position as a second blood vessel boundary candidate position; a boundary candidate selection part 9 which selects one of the first blood vessel boundary candidate position and the second blood vessel boundary candidate position; and an IMT measurement part 10 which performs IMT measurement on the basis of the tunica media-tunica externa boundary candidate position and the lumen tunica intima boundary candidate position of the selected blood vessel boundary candidate position.
