ABSTRACT:
A CT data processing apparatus and a CT data processing method capable of separating a subcutaneous fat region from a visceral fat region accurately and efficiently in CT data are provided. The CT data processing apparatus includes a center calculation part that calculates a body center41of an examinee on tomographic CT data, a start point setting part that identifies a vertebral column position45on the tomographic CT data and sets a start point on a muscular layer37on the opposite side of the vertebral column position45with respect to the body center41, a muscular layer determination part that determines whether or not the muscular layer37is present in a first range48, and when it is determined that the muscular layer37is present in the first range48, further setting a point on the muscular layer37in the first range48as a new first reference point47and thus determining whether or not the muscular layer37is present in the first range48, while moving the first reference point47from the start point46, and a separation line calculation part that calculates a separation line so that the separation line passes through the first reference points47.
