    摘要: A radiological imaging apparatus includes an imaging apparatus having an opening for insertion of a bed thereinto, and an attenuation correction data creating device. The imaging has a plurality of radiation detectors disposed around the opening and a plurality of gamma ray generation units residing between the opening and the radiation detectors disposed at a position nearest to the opening and being placed in a longitudinal direction of the bed. Each γ-ray generation unit has γ-ray sources of single photon emission nuclear species and is arranged to externally radiate a γ-ray alternately from either one of the γ-ray generators toward the opening. The data creator prepares attenuation correction data based on a detection signal as output from the radiation detector due to the incoming radiation of γ-rays from the γ-ray generator.

    摘要: A first γ-ray generating in a body, caused by a PET pharmaceutical, and a second γ-ray emitted from a γ-ray source and transmitting through the body are detected with a radiation detector. The emission image information (E image information), E1, E1 and E2, at each of patient motion phases, 0, 1 and 2, which divided a respiration period, are prepared by using each information obtained from the detected first γ-ray. The transmission image information (T image information), T0, T1 and T2, at each of patient motion phases, 0, 1 and 2, respectively, are prepared, by using each information obtained from the detected second γ-ray. Relative displacements, ([F10], [F20]), are determined by superimposing, on T image information T0, other T image information, T1 and T2. The E image information, E1, E2, are superimposed on the E image information E0, by using this relative displacement.

    摘要: A first γ-ray generating in a body, caused by a PET pharmaceutical, and a second γ-ray emitted from a γ-ray source and transmitting through the body are detected with a radiation detector. The emission image information (E image information), E0, E1 and E2, at each of patient motion phases, 0, 1 and 2, which divided a respiration period, are prepared by using information obtained from the detected first γ-ray. The transmission image information (T image information), T0, T1 and T2, at each of patient motion phases, 0, 1 and 2, respectively, are prepared, by using information obtained from the detected second γ-ray. Relative displacements, ([F10], [F20]), are determined by superimposing, on T image information T0, other T image information, T1 and T2.
