The types of diagnostically important images are discussed and the detectability of low contrast linear foci and unsharp nodular objects of low density is suggested as of prime importance. The comparison of chest films obtained using G4-RXO and Lanex-OGI with those obtained using conventional Hiscreen system was made concerning the visibility of some fine anatomical structures. G4 system showed increased noise and Lanex system showed slightly decreased contrast and were inferior to the latter. It is desirable to use the increased sensitivity of rare earth systems, permitting the shorter exposure times and smaller focal spots, to improve the image quality in such fields as pediatric radiography, (magnification) angiography, tomography, radiography using portable X-ray unit and photofluorography.
