ABSTRACT:
The present invention, in one form, is a method for performing image reconstruction from projection data acquired in a multislice helical scan. More specifically, a helical weighting factors is generated and then a modified weighting factor Wm(.beta.,.gamma.), which is a shifted and weighted average version of the helical weighting factor, is generated. The modified weighting factor is then applied to projection data.
