| Outline of Final Research Achievements |
Chest radiography is essential tool for diagnosis of pneumoconioses. Digital chest radiography is rather new technique which is implemented in most of the medical facilities in Japan that conduct health check up. Ministry of Health, Welfare and Labour Japan published digital version of Japan Standard Image for Classification of Pneumoconiosis as standard image for digital radiography. We aimed to compare the proposed image processing for pneumoconiosis and the usual image processing for other chest evaluation. We collected more than 2,000 images of pre-processing images and produced two images for pneumoconiosis evaluation and usual chest evaluation. Results showed both processed images were very close, but it suggested small opacities were more detected on Pneumoconioses processing and large opacities were well detected on usual processing.
