ULTRASOUND DIAGNOSTIC APPARATUS, CONTROL METHOD OF ULTRASOUND DIAGNOSTIC APPARATUS, AND PROCESSOR FOR ULTRASOUND DIAGNOSTIC APPARATUS

摘要

An ultrasound diagnostic apparatus (1) includes a B-mode processing unit (6) 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 (9) that displays the B-mode image; a vascular wall detection unit (10) that detects a vascular wall based on the B-mode image; a gate setting unit (11) that sets a Doppler gate in the blood vessel on the B-mode image; a Doppler processing unit (7) that acquires Doppler data in the Doppler gate; a blood flow velocity calculation unit (13) that calculates a blood flow velocity based on the Doppler data; and a blood flow rate measurement unit (12) 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.
