摘要： A long photomultiplier comprises a cylindrical main body having a light receiving face which extends in the longitudinal direction of the main body, a photocathode provided inside of the main body so that the photocathode extends along the light receiving face and emanates photoelectrons when exposed to light, and dynodes provided inside of the main body for multiplying the emanated photoelectrons. A reflection plate is provided facing and extending along the light receiving face, and the photocathode is positioned between the light receiving face and the reflection plate. The reflection plate is positioned for reflecting light, which has passed through the photocathode, toward the photocathode.

摘要： A method for reading radiation image information from a radiation image storage panel in which a radiation image information is recorded is performed by the steps of moving the storage panel on a plane of the storage panel with scanning on the storage panel in a direction perpendicular to the movement of the storage panel a pulse of stimulating light having a duty of 0.01 to 0.5; continuously detecting photoelectrically a stimulated emission appearing from the storage panel on the scanned surface and/or its back surface to obtain electric signals; sampling the electric signals at a timing synchronous with the scanned stimulating light pulse; and obtaining signals of the radiation image information from the sampled electric signals.

摘要： Stimulating rays produced by a line light source are linearly irradiated onto an area of a stimulable phosphor sheet, on which a radiation image has been stored, the stimulating rays causing the sheet to emit light in proportion to an amount of energy stored thereon during its exposure to radiation. Light emitted from the exposed linear area of the sheet is received with a line sensor comprising photoelectric conversion devices arrayed along each of a length direction of the linear area of the stimulable phosphor sheet and a direction normal to the length direction. The sheet is moved with respect to the line light source and the line sensor and in a direction different from the length direction of the linear area of the sheet. Operation processing is performed on outputs of the photoelectric conversion devices, which outputs have been obtained at respective positions of movement and correspond to an identical site on the sheet.
