In this study, Radiography detector is upgraded for patient who can't positioning properly. So many of medical center generally use wireless detector. In this situation, This analysis let know how difference between wire and wireless detector through the MTF value. measurement and method : 1. Setting the kvp and mAs using by phantom yetterbium 2. Measuring the contrast exposed equivalent material through the PACS 3. Calculating MTF Value that analyse resolution. Result : Wire detector MTF value higher than Wireless detector consistently SAMSUNG and DK. Conclusion : It seems to be having a gap between wire and wireless detector. Consideration should be given to various patient condition, useful wireless detector regardless of MTF value, because these difference can't affect medical reading.
