Abstract
The disclosure relates to a system and method for image reconstruction. The method may include the steps of: obtaining raw data corresponding to radiation rays within a volume, determining a radiation ray passing a plurality of voxels, grouping the voxels into a plurality of subsets such that at least some subset of voxels are sequentially loaded into a memory, and performing a calculation relating to the sequentially loaded voxels. The radiation ray may be determined based on the raw data. The calculation may be performed by a plurality of processing threads in a parallel hardware architecture. A processing thread may correspond to a subset of voxels.
Claims20
A method comprising:
- obtaining raw data corresponding to radiation rays within a volume;
- determining, among the radiation rays, a first radiation ray passing a plurality of voxels corresponding to a portion of the volume based on the raw data;
- grouping the plurality of voxels corresponding to the portion of the volume which are passed by the first radiation ray into a plurality of subsets, wherein at least a portion of the plurality of subsets of voxels are loaded into a memory;
- and
- performing a calculation relating to the loaded subsets of voxels by a plurality of processing threads in a parallel hardware architecture to generate an image of the volume.
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 at least one processor is configured to direct the system to perform operations including:
- obtaining raw data corresponding to radiation rays within a volume;
- determining, among the radiation rays, a first radiation ray passing a plurality of voxels corresponding to a portion of the volume based on the raw data;
- grouping the plurality of voxels corresponding to the portion of the volume which are passed by the first radiation ray into a plurality of subsets, wherein at least a portion of the plurality of subsets of voxels are loaded into a memory;
- and
- performing a calculation relating to the loaded subsets of voxels by a plurality of processing threads in a parallel hardware architecture to generate an image of the volume.
A method comprising:
- obtaining raw data corresponding to radiation rays within a volume;
- grouping a plurality of voxels corresponding to a portion of the volume into a plurality of subsets based on the raw data;
- loading the plurality of subsets of voxels into a memory such that at least some subsets of voxels are neighboring each other in the memory;
- and
- performing a calculation relating to the loaded subsets of voxels by a plurality of processing threads in a parallel hardware architecture to generate an image of the volume, wherein at least two neighboring subsets of voxels in the memory are accessed by neighboring processing threads in the parallel hardware architecture in the calculation.
