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, helical weighting factors are generated and then applied to the collected data. The helical weighting algorithm provides a high quality image with a low level or number of artifacts is described. Such algorithm also reduces the total time required to reconstruct such an image.
