Title:
IMAGE PROCESSING DEVICE AND METHOD FOR CONTROLLING IMAGE PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/107525
Kind Code:
A1
Abstract:
This image processing device (1) comprises: an accuracy calculation unit (13) that analyzes an ultrasonic image of a subject for each frame and calculates the accuracy of a blood vessel in the ultrasonic image; a blood vessel detection unit (16) that detects a blood vessel of which the accuracy calculated by the accuracy calculation unit (13) is higher than an accuracy threshold; and an accuracy threshold change unit (15) that changes the accuracy threshold on the basis of a plurality of pieces of accuracy calculated by the accuracy calculation unit (13) for ultrasonic images of a plurality of frames.
