This paper were studied the evaluation in compare with the conventional and AMBER of analog images, PACS and CR of digital images which were collected every ten sampling chest images with the J.J.Vucicuh chest evaluated chart, and were measured the chest phantom surface dose and the density of several part in chest images. The evaluated numbers were total 22 persons who were 6 persons of the M.D., 6 of the radiotechnological professors and 10 of the radiotechnologists. The obtained results summarized as following : 1. Approaching the optimum standard density of the several part in chest images drew near at the lung round region density in PACS images, the sternum region density in CR and AMBER images, the heart region density in CR AMBER images, the diaphram region density in AMBER and conventional images. 2. The evaluation measured surface dose were appeared orderly lesser dose at the AMBER images (spine 21 mR, lung 2mR, heart 12mR, apex 6mR) than the conventional images(32 mR), CR images(38mR) and PACS images(81mR). 3. The anatomical physical evaluation marks were taken the highest points at CR images(88.3), and orderly PACS images(82), AMBER images(79.2) and conventional images(65.2). 4. It is exposured with lesser surface dose at the analog images, but analog images leaves much room for image quality improvement, and digital images demand for lesser exposure surface dose, although excellent image quality.
