X선 사진의 판독 효율 향상을 위한 노출과 현상 기법에 관한 연구 = The Improvement of the Reading Efficiency for X-ray Photographs by Exposure and Development Techniques

다국어 초록 (Multilingual Abstract)

This study was conducted to improve the reading efficiency of X-ray Photographs by changing the development condition. To improve the reading efficiency, the characteristic curve was changed by varying the development conditions according to the condition of the image. The contrast was increased in the film with a low contrast, and decreased in the film with a high contrast. Using the normal X-ray filming method, the parts that are difficult to identify were emphasized. It was particularly effective for identifying minute cracks or internal structures. In addition, in the cases wherein the image cannot be represented in one film due to the difference in depth or thickness, the depth of the image was adjusted according to the unique range of the film to improve the reading efficiency of X-ray Photographs. This method can be applied to all X-ray filming subjects as well as cultural properties. Based on this technique, the image in the X-ray Photograph can be emphasized and the reading efficiency for the hard-to-detect parts can be increased. It seems that this would be very helpful for the X-ray Photograph analysis.
