Abstract
A nuclear medicine imaging apparatus according to an embodiment includes a gradation width storage, an estimating unit, and an image generating unit. The gradation width storage is configured to store the gradation width of an image determined by the temporal resolution of a detector. The estimating unit is configured to estimate the spatial position of a positron on the basis of the spatial position of a set of detectors and a set of detection times. The image generating unit is configured to allocate pixel value to pixels corresponding to the gradation width around the estimated spatial position such that a spatial resolution corresponding to the temporal resolution is reflected on a line linking the set of detectors, thereby generating an image.
Claims8
A nuclear medicine imaging apparatus comprising:
- a gradation width storage configured to store a gradation width of an image determined by the temporal resolution of a detector which detects radiation;
- an estimating unit configured to estimate the spatial position of a positron on a line linking a set of detectors which detect a pair of radiations emitted from the positron, on the basis of the spatial position of the set of detectors and a set of detection times when the set of detectors detect the pair of radiations;
- and
- an image generating unit configured to allocate pixel values to pixels corresponding to the gradation width which is stored in the gradation width storage around the spatial position estimated by the estimating unit such that a spatial resolution corresponding to the temporal resolution is reflected on the line linking the set of detectors, thereby generating an image.
A radiation therapy apparatus comprising:
- an emitting unit configured to emit a heavy particle beam;
- a set of detectors configured to detect a pair of radiations which is emitted with the energy emission of the heavy particle beam emitted from the emitting unit;
- a gradation width storage configured to store a gradation width of an image determined by the temporal resolution of the set of detectors;
- an estimating unit configured to estimate the spatial position of a positron on a line linking the set of detectors, on the basis of the spatial position of the set of detectors and a set of detection times when the set of detectors detect the pair of radiations;
- and
- an image generating unit configured to allocate pixel values to pixels corresponding to the gradation width which is stored in the gradation width storage around the spatial position estimated by the estimating unit such that a spatial resolution corresponding to the temporal resolution is reflected on the line linking the set of detectors, thereby generating an image.
