Before entering 21st Century, modern medical science is requiring more precise display which is highly estimated in diagnostic value as radial science technology is achieving sharp development. And it is also trying to contribute to improve national health and to offer better service by reducing radial exposure. General projection and Fluoroscopy which are most difficult to be displayed in digital tend to change their way ; from analog to digital with development of Electronic Engineering and Computer Technology, Introducing to CR system in 1994, SMC have displayed General projection and Fluoroscopy 100% in digital using CR system. This study searched differences between repeat rate, repeat type in the exam using Film/Screen and those in the exam using CR system. According to the analysis of repeat types and repeat rate of Film which was reused by using CR system in general projection room and Fluoroscopy room of SMC, we found that total 192,813 films were used and 2,097 films, 1.09% of total were reused. However, actual repeat covers 0.76% to 1,461 sheets with the exception of 636sheets. As above, display process using CR system is 0.76% much lower than general repeat rate 2$\sim$4% of Film/Screen exam. Besides decreased under/over exposure, it is appeared that position failure rate in repeat rate 0.76% covers relatively high 31%. Noticing that repeat caused unskilled devices handing was found many times, sufficient understanding seems to be required to reduce repeat.
