Graphics processing unit management system for computed tomography
| DWPI Title: Method for managing operation of graphics processing units in computer system, involves controlling writing of set of graphics data to storage system by output thread in computer system |
| Abstract: A method and apparatus for managing operation of graphics processing units in a computer system. A processing thread in the computer system controls processing of a set of sinogram data by a graphics processing unit to form a set of graphics data. An output thread in the computer system controls writing of the set of graphics data to a storage system. The graphics processing unit is available to perform processing of another set of sonogram data while the set of graphics data is written to the storage system such that the increased availability of a plurality of graphics processing units is present. |
| Use: Method for managing operation of graphics processing units in computer system, for use in computed tomography systems such as single-photon emission computed tomography (SPECT), positron emission tomography (PET) and holography, for managing graphics processing units to reconstruct slices from sets of sinogram data. |
| Advantage: The method recognizes and takes into account that currently used reconstruction processes for generating slices from sinogram data attempt to minimize the required memory footprint. The graphics processing unit performs processing of another set of sinogram data while the set of graphics data is written to the storage system such that increased availability of the graphics processing unit is present. Reduced processing times, increased energy efficiency, desired resource utilization, and other benefits are achieved. The process avoids setting the slicedepth to be to avoid eliminating the benefit to parallelizing the reconstruction. |
| Novelty: The method involves controlling (406) processing of a set of sinogram data by a graphics processing unit to form a set of graphics data by a processing thread in the computer system. The writing of the set of graphics data to a storage system is controlled (408) by an output thread in the computer system, such that the graphics processing unit is available to perform processing of another set of sinogram data while the set of graphics data is written to the storage system such that increased availability of several graphics processing units is present. |
