摘要： When a group of (pre-processed) projection data is stored into a projection-data storage unit, a Gaussian-based expansion-data creating unit creates a group of Gaussian-based expansion data that is expanded from each of the group of projection data through linear combination based on a plurality of Gaussian functions that is stored by a Gaussian-function storage unit and has different center points. A reconstruction-image creating unit then creates a reconstruction image by using the Gaussian-based expansion-data created by the Gaussian-based expansion-data creating unit, and stores the created reconstruction image into an image storage unit.

摘要： A PET apparatus includes an optical coupling detachment testing unit. In one example, the optical coupling detachment testing unit inputs an electric signal to a piezoelectric element or the like adhered to a detector module and generates a sound wave within the detector module. Further, the optical coupling detachment testing unit detects the sound wave propagated within the detector module and performs a frequency analysis on the detected sound wave. Subsequently, as a result of the analysis, the optical coupling detachment testing unit detects whether an optical coupling detachment has occurred by looking for a frequency distribution specific to a surface having an optical coupling detachment and/or comparing a frequency distribution with another frequency distribution from a previous test.

摘要： A positron emission computed tomography apparatus according to an embodiment includes a detector, a coincidence counting information generating unit, and a body movement detecting unit. The detector detects annihilation radiation released from a subject. The coincidence counting information generating unit searches for sets of counting information, which counted a pair of annihilation radiations at substantially the same time, from a counting information list that is generated from output signals of the detector; generates a set of coincidence counting information for each retrieved set of counting information; and generates a time series list of coincidence counting information. Based on the time series list of coincidence counting information, the body movement detecting unit detects temporal changes in the body movement of the subject.

摘要： A PET apparatus includes a clock unit. The clock unit includes: a time measuring unit that measures a time; and a reference time receiving unit that receives a reference time. The PET apparatus also includes a detection time revising unit. By using the reference time received by the reference time receiving unit, the detection time revising unit revises detection times recorded by using the time measured by the time measuring unit. For example, the detection time revising unit revises the detection times by calculating a time error that occurred during an image taking period of a predetermined image taking process by using the time measured by the time measuring unit and the reference time received by the reference time receiving unit and further distributing the calculated time error to each of the detection times recorded during the image taking period.
