ABSTRACT:
The present invention, in one form, is an apparatus for performing image reconstruction using data obtained by a four beam helical scan. In reconstructing an image, projection data arrays are generated. Such projection data is then weighted by weighting factors to generate a weighted projection data array. The weighted projection data array is filtered and back projected to generate an image data array. The image data arrays for the beams are then summed to generate a slice image data array.
