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： According to one embodiment, a nuclear medicine diagnosis includes a light signal generating unit, photodetection unit, measurement unit, calculation unit, and storage unit. The light signal generating unit repeatedly generates light signals. The photodetection unit repeatedly generates first output signals corresponding to intensities of the light signals, repeatedly generates second output signals corresponding to intensities of gamma rays emitted from a subject. The measurement unit repeatedly measures light signal detection times and repeatedly measures gamma ray detection times. The calculation unit calculates a difference between a target gamma ray detection time and a target light signal detection time of the light signal detection times for each of the gamma ray detection times. The target light signal detection time is measured before the target gamma ray detection time. The storage unit stores the calculated difference in association with a target second output signal of the second output signals.

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： According to one embodiment, a radiation therapy apparatus includes a radiation irradiation device, a detector included in a PET scanner, a control unit, and a PET image reconstruction unit. The radiation irradiation device emits a therapeutic radiation. The detector counts light derived from gamma rays, and is provided with a gap portion through which the therapeutic radiation passes on a plane of rotation about the body axis of a subject. The control unit controls the radiation irradiation device and the detector so as to rotate in synchronization with each other in a state capable of emitting the therapeutic radiation to the gap portion. The PET image reconstruction unit reconstructs a PET image based on position information at the time of counting of the detector that nearly coincidentally counts pair annihilation gamma rays in a state where the control unit performs rotation control.
