Radiation image read-out apparatus

摘要

A linear stimulating ray source produces stimulating rays and linearly irradiates them to a portion of a stimulable phosphor sheet, on which a radiation image has been stored. A photoelectric read-out system divides light, which is emitted from the portion of a front surface of the stimulable phosphor sheet exposed to the stimulating rays and/or the portion of a back surface of the stimulable phosphor sheet corresponding to the portion of the front surface exposed to the stimulating rays, into picture elements along a length direction of the portion exposed to the stimulating rays, and photoelectrically reads out the divided picture elements by arraying them in a two-dimensional form. A scanning system moves the stimulable phosphor sheet with respect to the linear stimulating ray source and the photoelectric read-out system and in a direction, which is approximately normal to the length direction of the portion exposed to the stimulating rays.
