Title:
FLUID ANALYSIS DEVICE, METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/131373
Kind Code:
A1
Abstract:
A fluid analysis device, method, and program, wherein a configuration is adopted in which fluid information such as a flow speed vector can be displayed at a suitable sampling interval. A processor analyzes an image acquired by imaging a subject that includes a tubular structure through the interior of which a fluid flows, and calculates fluid information pertaining to the flow of the fluid at each pixel position in the tubular structure. The processor derives the degree of matching between fluid information at a plurality of pixel positions of interest, which are set at a first sampling interval, and fluid information at a plurality of pixel positions within a predetermined region that is based on the pixel positions of interest inside the tubular structure included in the image. The processor sets, in accordance with the degree of matching a second sampling interval for use when displaying the fluid information. The processor samples the fluid information according to the set second sampling interval and displays the fluid information on a display.
