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) detecting a boundary line image pattern of an 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, the overlapping region corresponding to an overlapping area of the first stimulable phosphor sheet located on the side remote from the object, which overlapping area overlaps an overlapping area of the other second stimulable phosphor sheet located on the side close to the object, and ii) performing matching of positions of two radiation images, which have been read out from the two adjacent stimulable phosphor sheets respectively, with each other in accordance with the position of the detected boundary line image pattern in the first radiation image, which has been read out from the first stimulable phosphor sheet located on the side remote from the object, and the position of an edge of an overlapping region of a second radiation image, which has been read out from the second stimulable phosphor sheet located on the side close to the object, the overlapping region of the second radiation image corresponding to the overlapping area of the second stimulable phosphor sheet.
