Abstract
An ultrasound diagnostic apparatus () includes a first vascular wall detection unit () that detects a vascular wall in a minor axis direction by analyzing a B-mode image including a minor axis image of a blood vessel, a first blood vessel diameter calculation unit () that calculates a first blood vessel diameter from the vascular wall in the minor axis direction, a second vascular wall detection unit () that detects a vascular wall in a major axis direction by analyzing the B-mode image including a major axis image of the blood vessel, a second blood vessel diameter calculation unit () that calculates a second blood vessel diameter from the vascular wall in the major axis direction, a blood flow velocity calculation unit () that calculates a blood flow velocity based on Doppler data in a Doppler gate set on the B-mode image, and a blood flow rate measurement unit () that measures a blood flow rate based on the vascular wall in the major axis direction or the minor axis direction and the blood flow velocity, in which in a case where the second blood vessel diameter is within a determined range with respect to the first blood vessel diameter, the blood flow rate is automatically measured.
