Small patient size is a major factor of the difficulty in interpreting the newborn infant radiograph. Direct radiographic magnification can be employed to relieve this problem and special positioning devices were made to image the infant, confirmed to incubator and connected to life-supporting systems. The mobile X-ray equipment with a microfocus (0.2mm) radiographic tube, a rare-earth high-speed recording system and carbon cassette were combined to obtain a radiograph at magnification of 1.5-2.0. Image quality was superior to that of conventional contact radiographic system, but infant radiation exposure was 26% more than that of conventional study. Although direct radiographic magnification was very useful to recognize subtle or equivocal abnormality which could not be made from conventional image, it's application should be restricted to specific disease at this present, considering of infant radiation exposure. This technique will have wide clinical application when radiation exposure can be reduced by using other recording system such as Computed Radiography (CR).
