| 摘要 |
The present invention, in one form, is a system for performing image reconstruction using data acquired from a single detector row in a helical scan. More specifically, a modified weighting factor Wf( beta , gamma ), which is a shifted and weighted average version of the single slice helical weighting factor, is generated. The modified weighting factor is then applied to data to reduce image noise and artifacts and/or increase image sharpness.
