Abstract　： Recent improvements in computer science and medical imaging technology have been remarkable, and sampling, memory, and display of images are steadily moving into the era of digitalization. The characteristics of the system used this study are the simplicity of the procedure of digital X-ray image processing and the facilitation of analysis of the bone structure by use of the CR system, an existing digital X-ray diagnostic instrument. We evaluated "changes in the bone structure" using the new concept of "changes in the skeletal pattern" by combining the CR system, a two-dimensional digital X-ray imaging diagnostic instrument, with morphological filters to improve the precision of imaging diagnosis of bone diseases and developed a new analytical device to establish a computerized supporting system for bone morphology imaging diagnosis. As a result, we have devised, jointly with the RATOC System, an analytical system using a general-purpose personal computer rather than a large and expensive workstation, and are validating it by test running. In this study, we applied this analytical technique to the temporomandibular joint and evaluated the method for quantitative analysis of changes in the internal structure of the joint. The analytical system and the results are presented in this paper.
