1) Normal exposure time of conventional screen-film radiography for chest is about ~ 0.05 sec.
2) In the case of DDR Inventor-V, exposure time per line depends on scanning speed and is under 0.005 sec. at normal scan speed.
3) Therefore, effective exposure time of DDR Inventor-V is shorter than that of other radiography systems.
4) In addition, characteristics of MIC detector related to high image quality such as direct conversion, low scattered radiation and high fill factor contribute to low radiation dose on patients.
5) The film-screen and flat plate type detector cannot avoid the image distortion in vertical and horizontal directions.
6) DDR Inventor-V shows real size of image in the vertical direction.
