PURPOSE:To reduce mounting time by mounting two units of collimators after coupling these to a radiation detector. CONSTITUTION:U-shaped arms 4a, 4b are moved so as to space from each other in an arrow B direction to provide such a space in which a collimator carriage 8 for placing coolimators 9a, 9b between two units of radiation detectors 6a and 6b can be inseted, after which the detectors 6a, 6b, are rotated to position radiation detecting surfaces 6a, 6b in such a way that detecting surfaces 7a, 7b face each other. The collimators 9a, 9b are mounted respectively by moving the detectors 6a, 6b relatively. These are separated to the radiation detector 6a mounted with the collimator 9a and the detector 6b mounted with the collimator 9b by removing bolts and removing fixtures 10. |
