PURPOSE:To facilitate exchange of a radiation source by mounting a mount- removal part to a mounting member provided on a top plate and utilizing its sliding action of the plate together with the telescopic action of a telescopic tube part. CONSTITUTION:For mounting an accessory member for holding a detected body, a mount-removal part 21 can be removably mounted a mounting member 19 provided in a slidable roof plate 11. A telescopically movable supporting part 23, vertically lifted up from this mount-removal part 21, is adjusted in the length by an adjusting part 27. While a holding part 25 which can hold CT radiation source 7 is arranged in the telescopic tube part 23. By utilizing sliding action of this top plate and the telescopic action of the telescopic part, the radiation source, in a condition it is held to the holding member 25, can be freely vertically moved and slid, so that the radiation source can be easily exchanged without arranging a jig for exchanging the radiation source in a mounting bed. |
