Automatic Joint Space Distance Measurement Method for Rheumatoid Arthritis Medical Examinations

Rheumatoid arthritis is one of the diseases to narrow Joint Space Distance (JSD), while it is getting worth. The JSD has not been established to measure the JSD exactly, it is difficult to find the disease at the early stage. So, an application to measure the JSD has been developed, and it is possible to measure the JSD exactly. However, in this application, doctors have to process manually at a few points. Therefore, we propose an automatic measurement method for the rheumatoid application. The experimental results show that it is possible to measure joints automatically in X-ray images, which are taken clearly. Therefore, our proposed measurement algorithm is effective for rheumatoid arthritis medical examinations.
