Claim:
A PET-MRI hybrid system, comprising: a waiting room having a rail portion at a bottom thereof; an MRI room containing an MRI apparatus and having a rail portion aligned with the rail portion of the waiting room at a bottom thereof, the MRI room being divided from the waiting room by a shield door; a PET room containing a PET apparatus, the PET room being positioned to be opposed to the MRI room about the waiting room, wherein the rail portion of the waiting room is extended on a bottom of the PET room; a transfer unit for supporting a subject lying on an upper side thereof and traveling along the rail portions of the waiting room, the MRI room and the PET room, the transfer unit comprising a mover movable along the rail portions, a shuttle table horizontally sluably mounted to an upper side of the mover, and a cradle slidably mounted on an upper side of the shuttle table; and a bridge unit including a rail portion, the bridge unit selectively shiftable between a first position in which the rail portion of the bridge unit is displaced, providing a space for a movement of the shield door between the rail portion of the waiting room and the rail portion of the MRI room and a second position in which the rail portion of the bridge unit is connected with the rail portion of the waiting room and the rail portion of the MRI room, thereby allowing the transfer unit to be reciprocated between the waiting room and the MRI room.
