Title:
ULTRASOUND OBSERVATION DEVICE, METHOD FOR OPERATING ULTRASOUND OBSERVATION DEVICE, AND PROGRAM FOR OPERATING ULTRASOUND OBSERVATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/163827
Kind Code:
A1
Abstract:
Provided is an ultrasound observation device (3) which is designed to generate a plurality of ultrasonic images in chronological order on the basis of ultrasonic signals obtained by transmission and reception to and from an object to be observed by an ultrasonic transducer, and is provided with: a motion amount calculation unit (308) for calculating a motion amount which is an amount of motion of a subject captured in the ultrasonic image of the latest frame among the plurality of ultrasonic images relative to the subject captured in the ultrasonic image of a past frame; a reliability determination unit (309) for determining the reliability of the motion amount calculated by the motion amount calculation unit; and a freeze image selection unit (310) which, when a freeze instruction signal is received, selects a freeze image from the plurality of ultrasonic images on the basis of the motion amount and the reliability. Accordingly, the ultrasound observation device can appropriately select an image with little motion when an image is selected by a pre-freeze function.
