PURPOSE:To replace extremely easily a collimator by providing such as a scintillation camera with a collimator supporting member which supports pivotally and detachably both flanks of the collimator to a radiation incidence surface and a supporting means which is supported by a shore and supports the collimator supporting member in an elevating state. CONSTITUTION:A collimator 31 for a diagnosis is selected among various collimators stored in a collimator storage rack and supported with pins 30a and 30b of the collimator replacing device. Then, this collimator replacing device is conveyed to the detector 5 of a sincillation camera having the detector surface facing up by rotating the detector 5 so that the held collimator 31 approaches the surface of the detector 5. Guides 34 fixed under collimator support arms 29a and 29b are set on flanks of the detector 5 and the whole device is moved as shown by an arrow F. Then, the movement in the direction F is carried on until engaging notches 31a and 31b of the collimator 31 engage projections P formed on the detection surface of the detector 5 completely. |
