Abstract	We suggest a simple and efficient approach to reduce, and, in some cases, eliminate the windmill artifact. Our method does not require hardware changes. The idea is to improve the z-sampling by applying up-sampling in the detector row direction. One recent result show that the linear interpolation can be improved by shifting the samples by some small amount; we utilize this approach for our purposes. Evaluation shows that using some specified amount of the shift in interpolation, the proposed method provides a significant improvement of the windmill artifact with the clinical data, without a noticeable loss of z-resolution.
