Document Type and Number:
Japanese Patent JP2761667
Kind Code:
B2
Abstract:
A stimulable phosphor sheet, on which a radiation image has been stored, is scanned with stimulating rays in a main scanning direction and in a sub-scanning direction. The stimulating rays cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to radiation. The light emitted by the portion of the stimulable phosphor sheet exposed to the stimulating rays is photoelectrically detected, and an image signal representing the radiation image is thereby obtained. The speed, with which a stimulable phosphor sheet is scanned with the stimulating rays in the main scanning direction, is set to be the same for a plurality of stimulable phosphor sheets. The speed, with which a stimulable phosphor sheet is scanned with the stimulating rays in the sub-scanning direction, is set to be equal to a value inherent to each of the plurality of stimulable phosphor sheets. An image signal, which has been detected from each of the plurality of stimulable phosphor sheets, is processed, and a processed image signal is thereby obtained which represents a processed image wherein the resolution, with which the picture elements in the processed image are arrayed along the sub-scanning direction, is equal to a predetermined value.
