PROBLEM TO BE SOLVED: To provide an apparatus non-invasively and easily extracting the three-dimensional shape of the cartilage of a knee joint. SOLUTION: Volume data on the inside of a knee including the distal end of a femur 100 are obtained by scanning the knee of a person largely bent as the person is seated on a chair, etc., with an ultrasonic beam from a transducer part 40. The ultrasonic diagnostic apparatus extracts the tissue boundary by extracting the edge on the obtained volume data, and extracts a part corresponding to the contour of the cartilage from the extracted tissue boundary based on the specification by a user, etc. COPYRIGHT: (C)2010,JPO&INPIT
