[Development of all-in-one multi-slit equipment for measurements of the input-output characteristic of a phosphor plate].

An input-output characteristic curve is an essential piece of information for analyzing medical images taken using a phosphor plate. In the multi-slit method, an actuator moves shields that have numerous slits during X-ray irradiation. Numerous data can be measured by one-time irradiation, so the fading effect is negligibly small. This method was recently proposed by Takegami et al., but their equipment consisted of large multiple compositions. The aim of this study was to fabricate a new handy type equipment that combines multiple productions into one small production. In this paper, we propose an idea for downscaling the size of the equipment, and report that the same input-output characteristic is obtained using our newly proposed method.
