    Abstract: A method and system may be implemented, according to a preferred embodiment of the present invention, to permit transformation of software to use conditional execution instructions. According to the preferred embodiment, a system and method is provided to transform machine instructions (for example, machine instructions generated by a source code compiler) to make use of the conditional execution features of a processor. The preferred embodiment thus reduces code size and better utilizes the instruction pipeline and cache.

    Abstract: A method for memory reclamation is disclosed that includes marking a memory object when an attempt to alter a reference to the memory object is detected by a software write barrier. Marking be by using representations (“black,” “white”, “gray”) stored as part of a garbage collection information data structure associated with each memory object. Initially, all allocated memory objects are marked white. Objects are then processed such that objects referenced by pointers are marked gray. Each object marked gray is then processed to determine objects referenced by pointers in it, and such objects are marked gray. When all objects referenced by pointers in the selected gray objected have been processed, the selected gray object is marked black. When all processing has been completed, objects still marked white may be reclaimed. Also described is a garbage collector which runs as a task concurrently with other tasks. A priority of the garbage collector may be increased to prevent interruption during certain parts of the garbage collection procedure.

    Abstract: The present invention, in one form, is a system for performing image reconstruction from projection data acquired in a helical scan. More specifically, the system implements an incremental reconstruction algorithm for helical scan projection data which does not require filtering, weighting and backprojecting such projection data for generating each image. Particularly, a segmentation algorithm divides the projection into a plurality of segments so that subsequent images are generated by generating image data only for those segments that have changed from the base image.

    Abstract: A system and method for dual energy CT spectral imaging that provides for accurate blood vessel stenosis visualization and quantification is disclosed. The CT system includes an x-ray source configured to project x-rays toward a region-of-interest of a patient that includes a blood vessel in a stenosed condition and having a plaque material therein. The CT system also includes an x-ray detector to receive x-rays emitted by the x-ray source and attenuated by the region-of-interest, a data acquisition system (DAS) operably connected to the x-ray detector, and a computer programmed to obtain a first set of CT image data for the region-of-interest at a first chromatic energy level, obtain a second set of CT image data for the region-of-interest at a second chromatic energy level that is higher than the first chromatic energy level, and identify plaque material in the region-of-interest by analyzing the second set of CT image data.
