| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Diagnostic standard of osteoporosis of the Japanese Society for Bone and Mineral Research has proposed to diagnose osteoporosis by visual interpretation of bone contraction degree on lateral lumber plain X-ray and measurement of bone density using Dual Energy X-ray Absorptiometry (DXA) method. However doctor’s experience and knowledge might affect those results. Therefore, a method that osteoporosis can be diagnosed objectively is required. In this paper, the method for Computer-Aided Diagnosis of osteoporosis is proposed. Using public domain software, ImageJ, we evaluate bone contraction degree by spatial frequency analysis of region of interest (ROI) (64×64matrix) on the lateral view of third lumbar vertebrae of digital radiographs. Digital radiographs of 48 patients are examined with standardization integrated power values calculated by power spectrum values of the 2 dimension Fast Fourier Transform (2DFFT). As the result of the analysis on these values, it is found that evaluation of osteoporosis can be performed by the Computer-Aided Diagnosis using the proposed method. | |
