[Comparative studies on physical characteristics and clinical efficacy of conventional and digitized chest radiographs].
Comparative studies were performed between digitized and conventional radiographs of the chest in terms of their physical characteristics and diagnostic efficacy. The purpose of these studies is to confirm the diagnostic capability of digitized image whether it can use for primary diagnosis in routine works. The results of two studies show good correlation each other. It is strongly suggested that the conventional chest radiographs should be digitized with 100 microns pixel in 12 bit density resolution.
