1. An ultrasound diagnostic apparatus comprising:
a display; and
a processor configured to
acquire a B-mode image in which at least a blood vessel region is imaged;
display the B-mode image on the display;
set a Doppler gate within the blood vessel region on the B-mode image, the Doppler gate having an upper gate point and a lower gate point which face each other along a scan line passing through a center point of the Doppler gate;
set an upper detection region extending in a shallow portion direction from an upper projection point obtained by projecting the upper gate point on a blood flow perpendicular line that passes through the center point of the Doppler gate and extends perpendicular to a blood vessel gradient;
set a lower detection region extending in a deep portion direction from a lower projection point obtained by projecting the lower gate point on the blood flow perpendicular line;
detect an anterior vascular wall on a basis of an intensity of a B-mode image signal at each point in the upper detection region; and
detect a posterior wall on a basis of an intensity of a B-mode image signal at each point in the lower detection region.
