<p>A gantry (2) and pallet (90) assembly using scintillation cameras (46) to acquire data emitted from radiopharmaceuticals previously introduced into a patient. The radiopharmaceuticals accumulate in a predetermined region of interest within the patient. The gantry (2) can perform both whole body and single photon emission computed tomograph (SPECT) scans. The gantry (2) has two scintillation cameras (46) mounted in a diametrically opposed manner on and in close proximity to a rotation ring (24). Each camera (46) can be radially translated relative to the rotation ring (24) simultaneously with the rotation of the rotation ring (24). The gantry (2) is capable of being translated along a pair of translation tracks (12) so that a pallet (52, 54) upon which a patient lies passes therethrough. The pallet assembly (90) has a storage carriage which supports a substantially rectangular flat pallet (52) upon a slidable frame (68), and a curved pallet (54) upon an extension assembly (68). The storage carriage (50) can be slid away from the gantry (2) or close to the gantry (2). When the storage carriage (50) is close to the gantry (2) either pallet (52, 54) can be easily transferred to a vertically adjustable pallet support (110, 112) used during scanning procedures.</p> |
