ULTRASONIC MEASUREMENT APPARATUS AND ULTRASONIC MEASUREMENT METHOD

摘要

Scanning lines immediately above the blood vessel are detected using received signals of reflected waves obtained when ultrasonic waves transmitted to the blood vessel are reflected from the blood vessel, and candidates at depth positions that seem to be front and rear walls of the blood vessel are detected based on the received signals of the scanning lines. Then, vascular front and rear walls pairs of front and rear walls are narrowed down from the candidates, and the narrowed-down vascular front and rear walls pair is regarded as one blood vessel and artery/vein identification is performed for each blood vessel. Measurement of vascular function information is performed for the blood vessel determined to be an artery.

主权项

1. An ultrasonic measurement apparatus, comprising:
a transmission and reception control unit that controls transmission of ultrasonic waves to a blood vessel and reception of reflected waves that are reflected from the blood vessel; a front and rear walls detection unit that detects front and rear walls of the blood vessel using received signals of the reflected waves; and a type determination unit that determines a type of the blood vessel using a temporal change in a distance between the front and rear walls.
