Document Type and Number:
Japanese Patent JP2565779
Kind Code:
B2
Abstract:
In a radiation image read-out apparatus, a stimulable phosphor sheet, on which a radiation image has been stored, is exposed to stimulating rays, which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to radiation. The emitted light is photoelectrically detected and converted into an image signal representing the radiation image. An ultraviolet lamp is provided, which produces ultraviolet rays such that energy from the ultraviolet rays is approximately uniformly stored on a stimulate phosphor sheet. The image signal is corrected in accordance with information about the characteristics of shading. The information about the characteristics of shading is corrected in accordance with a signal detected from a stimulable phosphor sheet, on which the energy from the ultraviolet rays have been approximately uniformly stored.
