Abstract
An ultrasonic measurement apparatus detects a plurality of feature points in a B-mode image acquired by ultrasonic measurement. The feature point detection is repeatedly performed for each measurement frame. Then, a displacement vector of each feature point between measurement frames that are temporally adjacent (consecutive) to each other is calculated. Then, a displacement direction is calculated based on the displacement vector for each feature point. An intersection of the displacement direction lines is detected as a cross-sectional center position of a blood vessel.
