1. A method of manufacturing radiation tomography apparatus having a group of detectors in an annular shape, the group of detectors having detector arrays in a ring shape with each of radiation detectors arranged in series in which a scintillator that converts radiation into fluorescence, a light guide that receives fluorescence, and a light detector that detects fluorescence are laminated in a height direction, comprising:
a detector array formation step of forming a detector array having two or more radiation detectors integrated with one another; a first holding member fixation step of fixing a sub member of a holding member, the holding member having a main member and the sub member, the sub member extending from the main member to a base of a first jig, the first jig also having a branch portion and a supporting device, the branch portion of the first jig extending from the base of the first jig; a detector array placement step of placing the detector array on the first jig by inserting the detecting array into a position between the branch portion and the main member; a second holding member fixation step of fixing the detector array to the holding member by adjusting relative positions of the detector array and the holding member with respect to the base by spacing the scintillator apart from the base through contact of the scintillator of the detector array to the supporting device; and a group of detectors formation step of forming the group of detectors by fixing the sub member to a base member to arrange the detector arrays at least in a circular shape. |
