－Establishment of X-ray Diagnostic Imaging and its Digitization－

Abstract

Current medical care is supported by image diagnosis by PACS. Although its beginning is in the finding of X-rays, in order to establish it as a diagnostic imaging method, it was necessary to solve the X-ray scattering problem by the human body. The next tasks were high sensitivity for reduction of exposure dose, rapid processing for immediacy, high image quality for improving diagnostic performance, but they were solved with screen and film improvements. Digitization is on an extension of these tasks, resulting in image acquisition by CR and DR and image display by dry imager and by flat-panel display.
