CARTILAGE QUANTIFICATION DEVICE, CARTILAGE QUANTIFICATION METHOD, AND CARTILAGE QUANTIFICATION PROGRAM

摘要

A region extraction unit extracts a bone region and a cartilage region from a three-dimensional image. A projection direction determination unit determines a projection direction of the cartilage region and a projection image generation unit projects the bone region and the cartilage region in the determined projection direction and generates a projection image. A quantification unit calculates a quantitative value of the cartilage region on the projection image.
