  • High speed Z-smoothing method and apparatus for CT imaging system
    Publication number: 20030097063
    Abstract: A method and apparatus for quickly rendering thick CT slice images wherein the data corresponding to an optimal number of slice images to be combined to generate a thick image and the data set required to generate the thick image are determined as a function of an optimal Z-smoothing factor and wherein Z-smoothing is implemented in software that performs quickly and is useable with any helical weighting algorithm and Z-smoothing function.

  • Row-wise full helical view weighting method and apparatus for CT scanners
    Patent number: 6522714
    Abstract: A method and apparatus for performing image reconstruction using data obtained by an N beam helical scan, the method including generating projection data arrays for each of the N row in a CT detector, weighting the data arrays using a unique weighting function that is applicable to detectors having many different numbers of rows N to generate helical weighted arrays for each row, weighting the helical weighted arrays by applying a conjugate weighting function to generate conjugate arrays for each detector row and then combining the conjugate weighted arrays, filtering and back-projecting to generate a slice image.
