    摘要： An apparatus for separating gas bubbles that may be entrained in perfusate flow prevents such bubbles from continuing downstream and entering an organ or tissue. The apparatus may include a chamber having a top wall, a bottom wall and side walls. The chamber may include an inlet configured to allow at least one of gas and liquid to enter the chamber, an air opening configured to allow at least gas to exit the chamber and a first liquid opening configured to allow at least liquid to exit the chamber. The apparatus may function as an accumulator that reduces or eliminates pulsatility of the liquid flow and pressure. The apparatus may include a minimum volume of gas, initially or through the accumulation of gas, such that flow and pressure fluctuations in the liquid are dampened or eliminated. The apparatus may include a sampling port in a wall of the chamber.

    摘要： A gantry and pallet assembly using scintillation cameras 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 can perform both whole body and single photon emission computed tomograph (SPECT) scans. The gantry has two scintillation cameras mounted in a diametrically opposed manner on and in close proximity to a rotation ring. Each camera can be radially translated relative to the rotation ring simultaneously with the rotation of the rotation ring. The gantry is capable of being translated along a pair of translation tracks so that a pallet upon which a patient lies passes therethrough. The pallet assembly has a storage carriage which supports a substantially rectangular flat pallet upon a slidable frame, and a curved pallet upon an extension assembly. The storage carriage can be slid away from the gantry or close to the gantry. When the storage carriage is close to the gantry either pallet can be easily transferred to a vertically adjustable pallet support used during scanning procedures.
