Title:
ULTRASONIC DIAGNOSTIC DEVICE, IMAGE PROCESSING DEVICE, AND IMAGE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/080833
Kind Code:
A1
Abstract:
An ultrasonic diagnostic device of an embodiment of the present invention is provided with a setting section (172) and a tracking section (173). The setting section (172) sets a 2D or 3D interest region in ultrasonic image data of at least one time phase from among the video data of gathered 2D or 3D ultrasonic image data where the image pick-up target is a region that includes tissue that moves. The tracking section (173), which serves as an estimation section, uses the ultrasonic image data of the remaining time phases other than the at least one time phase in a section in which the video data was gathered to acquire the following: first positional information of a region that was estimated on the basis of motion information to be the interest region; and second positional information of a region that was estimated on the basis of information other than the motion information to be the interest region. The tracking section (173) acquires, as the positional information of the interest region, positional information in which the first positional information and the second positional information are combined on the basis of a reliability indicator pertaining to the reliability of the motion information, and the tracking section tracks such interest region.
