Ultrasound diagnostic apparatus, control method of ultrasound diagnostic apparatus, and processor for ultrasound diagnostic apparatus

Abstract

An ultrasound diagnostic apparatus () includes a B-mode processing unit () that generates a B-mode image in which at least a blood vessel is imaged based on a reception signal obtained by transmitting and receiving ultrasonic waves to and from a subject; a display device () that displays the B-mode image; a vascular wall detection unit () that detects a vascular wall based on the B-mode image; a gate setting unit () that sets a Doppler gate in the blood vessel on the B-mode image; a Doppler processing unit () that acquires Doppler data in the Doppler gate; a blood flow velocity calculation unit () that calculates a blood flow velocity based on the Doppler data; and a blood flow rate measurement unit () that measures a blood flow rate based on the detected vascular wall and the calculated blood flow velocity, in which the blood flow rate is automatically measured based on a fixed start trigger.
