摘要： This invention has one object to provide a method of collecting calibration data in radiation tomography apparatus that allows reliable collection of calibration data with a wide detector ring. In order to achieve this purpose, in the method of collecting calibration data in radiation tomography apparatus according to this invention, the number of coincidence events is obtained while the phantom that emits annihilation gamma-ray pairs moves as to pass through an inner hole of the detector ring. Such configuration dose not need the phantom having a width equal or larger than the detector ring, and may realize reliable collection of calibration data. Moreover, it may be considered that annihilation gamma-ray pairs have been emitted in uniform property without depending on positions of the detector ring. As a result, calibration data that is more suitable for removal of a image artifact may be obtained.

摘要： One purpose of this invention is to provide radiation tomography apparatus with easier maintenance. A specific approach for this purpose is as follows. That is, a detector ring in the radiation tomography apparatus includes two or more rings. Moreover, a ring moves as to approach a next ring, whereby both the rings are connected. If radiation tomography is conducted while a clearance is provided between the rings, detection sensitivity of the detector ring decreases due to the clearance. On the other hand, according to this invention, the ring moves as to approach the next ring, which results in a narrower clearance. Accordingly, radiation that is not observed may be reduced as much as possible.

摘要： This invention has one object to provide radiation tomography apparatus that allows suppression of arithmetic load of detection data with a wider detector ring. In order to achieve this purpose, the radiation tomography apparatus according to this invention performs coincidence only when two scintillation counter crystals that detect gamma rays coincidentally (A) belong to the same ring unit, or (B) belong to each of the ring units adjacent to each other. Accordingly, a distance in the central axis direction between the radiation detecting elements is limited to be equal to or less than a thickness of the ring unit in the central axis direction. Accordingly, radiation tomography apparatus may be provided that allows generation of the sectional image suitable for diagnosis while arithmetic load is suppressed.

摘要： This invention has one object is to provide radiation tomography apparatus that allows production with low price through suppression in number of radiation detectors to be mounted. One of the detector rings in this invention is a first detector ring having a sufficient internal diameter to introduce shoulders of the subject M, and the other is a second detector ring having a smaller internal diameter than the first detector ring. In so doing, the radiation detectors forming the detector ring may be suppressed in number, which may provide radiation tomography apparatus of low price. Moreover, a smaller diameter of the detector ring may result in improved spatial resolution and detection sensitivity of radiation.

摘要： In a state in which a subject is absent, blank data is collected by a self-radioactivity element typified by Lu-176 (S1). In a state in which the subject is present, transmission data is collected by the self-radioactivity element (S2). Emission data is collected by γ rays emitted from the subject injected with a radiopharmaceutical (S3). Absorption-corrected data is calculated based on the blank data and the transmission data (S4 to S7), and the emission data is absorption-corrected using the absorption-corrected data (S8). Although such background data obtained by the self-radioactivity is originally abandoned, the background data is rather used for the absorption-corrected data. Stable absorption correction can be thereby conducted.
