摘要:
A method for detecting radiation image which comprises steps of: causing a radiation image storage panel which comprises a phosphor layer containing a stimulable phosphor to absorb a radiation having passed through an object or radiated from an object. placing said radiation image storage panel and a photosensor composed of numerous photosensitive elements in regular and two-dimensional arrangement together in layers, and irradiating the panel with an electromagnetic wave to release the radiation energy stored in the panel as stimulated emission; and photoelectrically detecting the stimulated emission with said photosensor. A method for detecting radiation image using a radiation image detector which comprises a photosensitive member composed of numerous photosensitive member composed of numerous photosensitive elements and a phosphor layer containing a stimulable phosphor provided thereon is also disclosed.
