다국어 초록 (Multilingual Abstract)

Recently, interests and utilization on Computed Radiography (CR) and Digital Radiography (DR) have tended to increase owing to an introduction of Picture Archiving and Communication System (PACS) and an accuracy control of special medical equipment for breast imaging. The present paper compared the breast image of Film-Screen methods and DR methods using the breast photographing system for accuracy of breast cancer diagnosis. We use Mammo phantom and photograph in F/S System methods and DR System methods. Each image uses the basis of assessment of evaluation tests and 10 people radiation students are visible fiber, Calcification and mass degree score. It compared the average score of each received image, then it classified the above schedule score with passing. The cellulose (fiber), the calcareous sinter (calcification)and the bell lump (mass) received a high score in DR and Film-Screen methods order. In this study, the breast image of DR methods had a better picture quality compared to the breast image of Film-Screen methods, and had received high score from all items. In DR methods, the image quality was dependent on the monitor resolution. The higher the monitor resolution, the better the quality of the image produced. According to quality control in Film- Screen methods, we found out that there was a decrease in the quality of the picture being produced.
