Technologies of Digital Imaging Materials for Medical Diagnosis

Abstract

In recent days, digitalizing of the imaging for medical diagnosis is rapidly spread along with progress of image diagnostic technology such as CR/CT and infrastructure improvement of hospital. The digital imaging materials, especially dry imaging materials which have no use for wet developing process become increasingly important. Dry imaging materials for medical diagnosis are categorized as phtotothermal system and direct thermal system. Photothermal and thermal system have features on number of pixels, system size and throughput respectively. Photothermal system is suitable for integrated processing in major hospitals. Thermal system is suitable for small hospitals, clinics and dispersed processing in each department in major hospitals. Technologies demanded on each system are wide dynamic range, high throughput, processing stability and evenness of image density, arcival ability of image and neutral gray of image tone for suitable as the medical diagnostic image. Technologies of these two systems for contributing these demands are illustrated.
