    摘要: In an open-type PET scanner including a plurality of detector rings having multiple rings arrayed in the body axis direction, radiation measurement is performed while at least one detector ring is relatively moved with respect to a subject in the body axis direction, thereby dispersing simultaneous radiation in an open region to suppress a local reduction in sensitivity. The detector rings are optimized in constitution, moving direction and/or moving speed, thus making it possible to reduce the variation of distribution of sensitivity and expand a clearance in the open region and a field-of-view in the body axis direction.

    摘要: A medium area (S) filled with liquid xenon (2) is formed between an external cylindrical body (1a) and internal cylindrical body (1b), and a pair of anode pads (11, 12) are disposed in two-dimensional form in opposite end portions of the medium area (S) in the intersection direction with respect to the gamma-ray incident direction. An intermediate electrode (10) is disposed between a pair of anode pads (11, 12), and a plurality of photomultiplier tubes (5) is installed in two-dimensional form in the external cylindrical body (1a). Then, the gamma-ray reaction point within the liquid area (S) is identified from signals output from the anode pads (11, 12) and photomultiplier tubes (5).

    摘要: In a case where an error is included in measurement data corresponding to one or a plurality of detecting elements in a tomography scanner, a system matrix to be calculated or referenced on image reconstruction calculation is corrected in accordance with the error. Thus, even when an error such as a defect or a fault occurs in a detector, influence of the error is eliminated, thereby reducing an artifact generated in an image. At that time, positional information of the detecting elements including the error and information on the degree of the error are stored in a storage device and referenced inside image reconstruction software, thus making it possible to correct the system matrix in accordance with the error.
