Abstract
The disclosure relates to a system and method for reconstructing a PET image. The method may include: obtaining PET data relating to an object collected by a plurality of detector units; determining functional status of the plurality of detector units; generating reconstruction data based on the functional status of the respective detector units and the PET data; and reconstructing a PET image based on the reconstruction data.
Claims17
A method implemented on at least one device each of which has at least one processor and storage, the method comprising:
- obtaining scan data relating to an object collected by a plurality of detector units;
- determining functional status of the plurality of detector units;
- dividing the plurality of detector units into a first group and a second group based on the functional status of the respective detector units, wherein the functional status of the detector units in the first group is functional, and the functional status of the detector units in the second group is non-functional;
- generating reconstruction data based on the scan data collected by the detector units in the first group;
- and
- reconstructing an image based on the reconstruction data.
A system, comprising:
- at least one storage medium including a set of instructions;
- and
- at least one processor configured to communicate with the at least one storage medium, wherein when executing the set of instructions, the system is configured to:
- obtain scan data relating to an object collected by a plurality of detector units;
- determine functional status of the plurality of detector units;
- divide the plurality of detector units into a first group and a second group based on the functional status of the respective detector units, wherein the functional status of the detector units in the first group is functional, and the functional status of the detector units in the second group is non-functional;
- generate reconstruction data based on the scan data collected by the detector units in the first group;
- and
- reconstruct an image based on the reconstruction data.
A non-transitory computer readable medium storing instructions, the instructions, when executed by a computing device, causing the computing device to implement a method, comprising:
- obtaining scan data relating to an object collected by a plurality of detector units;
- determining functional status of the plurality of detector units;
- dividing the plurality of detector units into a first group and a second group based on the functional status of the respective detector units, wherein the functional status of the detector units in the first group is functional, and the functional status of the detector units in the second group is non-functional;
- generating reconstruction data based on the scan data collected by the detector units in the first group;
- and
- reconstructing an image based on the reconstruction data.
