Title:
BLOOD FLOW FIELD ESTIMATION APPARATUS, LEARNING APPARATUS, BLOOD FLOW FIELD ESTIMATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/172280
Kind Code:
A1
Abstract:
Provided is a blood flow field estimation apparatus comprising an estimation unit and an output unit. The estimation unit estimates a blood flow field in an organ of an estimation target on the basis of organ tissue three-dimensional structure data of the organ of the estimation target by using a learned model obtained in advance by machine learning of a relation between the organ tissue three-dimensional structure data and the blood flow field in the organ, the organ tissue three-dimensional structure data including image data of a plurality of organ sectional images that are images of a section of the organ and images having pixels in which the bit depth is 2 or more, and picture position information that is information indicating a picture position in the organ taken in the organ sectional image. The output unit outputs an estimation result of the estimation unit.
