ULTRASOUND MEASUREMENT APPARATUS AND ULTRASOUND MEASUREMENT METHOD

摘要

A region of interest which is considered to be a vascular wall of an artery is set in a B-mode image, and tracking processing is performed for each region of interest. A maximum displacement velocity Vu in a positive direction and a maximum displacement velocity Vd in a negative direction are obtained as a peak value of a displacement velocity of the vascular wall. If a first peak ratio (Vu/Vd) of a region of interest corresponding to an anterior wall is equal to or greater than a predetermined first feature threshold value (for example, 2.0) using the obtained maximum displacement velocity Vu in the positive direction and maximum displacement velocity Vd in the negative direction, it is determined that the region of interest is an artery.

主权项

1. An ultrasound measurement apparatus comprising:
a vascular wall tracking unit which tracks the position of a vascular wall of a blood vessel in a biological tissue on the basis of a reflected wave signal of an ultrasonic wave radiated toward the living body; a determination unit which determines whether or not the blood vessel to be tracked is an artery on the basis of whether or not positional change of the vascular wall to be tracked is positional change of a vascular wall of an artery; and a report unit which reports the determination result of the determination unit.
