  • Publication number: 20080118021
    Abstract: Methods and apparatus for reconstructing a multiple resolution images of an object are provided. The method includes reconstructing a first three-dimensional image at a first resolution, determining at least one volume of interest in the generated image, and reconstructing a second three-dimensional image of the determined at least one volume of interest at a second resolution, the second resolution being higher than the first resolution such that a quantification of image structures is facilitated.

  • Publication number: 20080119713
    Abstract: Methods and apparatus for coding a visual representation of one or more plaque regions in a vessel are provided. The method includes segmenting the visual representation of the vessel to identify structures associated with the vessel, classifying at least one region in the vessel as a plaque region, displaying the at least one plaque region using a visual highlight selectively associated with the classification for the at least one plaque region, and shading the visual highlight based on a probability that the classification is correct.

  • Publication number: 20070127797
    Abstract: Methods and systems for generating computed tomographic (CT) images from image data acquired during different biological cycles are provided. A computer is programmed to receive a plurality of scan data acquired during a gated acquisition window of each of a plurality of biological cycles, blend the scan data acquired during a first of the plurality of biological cycles with the scan data acquired during a second of the plurality of biological cycles, and construct a final image from the blended data.

  • Patent number: 7120905
    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.

  • Publication number: 20060018439
    Abstract: A method for producing an image of an object includes scanning an object with an imaging apparatus to collect projection data of the object utilizing cone sampling. The projection data is rebinned in a row-wise, fan-to-parallel fashion to produce rebinned data and the rebinned data is view-weighted to produce view-weighted data. The method further includes filtering the view-weighted data utilizing a row-wise ramp filter to produce filtered data and generating an image of the object utilizing the filtered data and a three-dimensional (3D) backprojection.

  • Patent number: 6874074
    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.

  • Publication number: 20040156897
    Abstract: A new oral polymeric controlled release formulation suitable for the once-a-day administration of valproate compounds, such as divalproex sodium, has been discovered. This formulation exhibits significant advantages over the sustained release valproate formulations of the prior arts. This formulation minimnizes the variation between peak and trough plasma levels of valproate over a 24 hour dosing period. This formulation follows a zero-order release pattern thus producing essentially flat plasma levels of valproate, once steady-state levels have been achieved. This results in a significantly lower incidence of side effects for patients consuming such a formulation.

  • Patent number: 6775347
    Abstract: A method for reconstructing an image of an object includes generating a plurality of projection data, helically interpolating the projection data, rebinning the helically interpolated projection data from a fan-beam format to a parallel-beam format, and reconstructing an image of the object using the parallel-beam format projection data.
