Abstract:
A connection processing method for radiation images, in which a single radiation image of an object is recorded on a plurality of stimulable phosphor sheets associated with one another such that portions of two adjacent stimulable phosphor sheets overlap each other, and in which connection processing is performed on a plurality of radiation images having been read out from the plurality of the stimulable phosphor sheets respectively, such that the single radiation image of the object is reconstructed from the plurality of the read-out radiation images, the method comprising the steps of:i) as for at least a certain area within overlapping regions of two radiation images having been read out from the two adjacent stimulable phosphor sheets, which overlapping regions correspond to overlapping areas of the two adjacent stimulable phosphor sheets, employing an area within the overlapping region of a first radiation image having been read out from a first stimulable phosphor sheet located on the side remote from the object, which first stimulable phosphor sheet is one of the two adjacent stimulable phosphor sheets, and ii) making an image density correction such that an image density of the area within the overlapping region of the first radiation image, which area is employed as at least the certain area within the overlapping regions of the two radiation images having been read out from the two adjacent stimulable phosphor sheets, approximately coincides with the image density of a non-overlapping region of the first radiation image other than the overlapping region and/or the image density of a second radiation image having been read out from a second stimulable phosphor sheet, which is located on the side close to the object.
