Abstract
A nuclear medicine diagnostic apparatus according to an embodiment includes a nuclear medicine detector and processing circuitry. The nuclear medicine detector includes a plurality of detection devices that detect gamma rays. The processing circuitry controls a change from a first relative position of the nuclear medicine detector and a subject to a second relative position that is separate from the first relative position by a distance smaller than a device size of the detection device, collects first data in the first relative position, collects second data in the second relative position, and reconstructs a nuclear medicine image based on the first data and the second data.
Claims6
A nuclear medicine diagnostic apparatus, comprising:
- a nuclear medicine detector including a plurality of detection devices that detect gamma rays;
- and
- processing circuitry configured to control a change of a position of the nuclear medicine detector relative to a subject from a first relative position to a second relative position, the second relative position being separated by a distance from the first relative position in a direction along a surface of the nuclear medicine detector that receives the gamma rays, the distance being smaller than a device size of one of the detection devices in the direction, collect first data in the first relative position, collect second data in the second relative position, and reconstruct a nuclear medicine image based on the first data and the second data.
A nuclear medicine imaging method, comprising:
- controlling a change of a position of a nuclear medicine detector relative to a subject from a first relative position to a second relative position, the second relative position being separated by a distance from the first relative position in a direction along a surface of the nuclear medicine detector that receives gamma rays, the distance being smaller than a device size of one of a plurality of detection devices in the direction;
- collecting first data in the first relative position and collecting second data in the second relative position;
- and
- reconstructing a nuclear medicine image based on the first data and the second data.
A non-transitory computer-readable storage medium that stores a nuclear medicine imaging program that causes a computer to perform a method comprising:
- controlling a change of a position of a nuclear medicine detector relative to a subject from a first relative position to a second relative position, the second relative position being separated by a distance from the first relative position in a direction along a surface of the nuclear medicine detector that receives gamma rays, the distance being smaller than a device size of one of a plurality of detection devices in the direction,
- collecting first data in the first relative position and collecting second data in the second relative position, and
- reconstructing a nuclear medicine image based on the first data and the second data.
