Abstract

In helical cone-beam computerized tomography, the data within the Tam-Danielsson window is sufficient for exact reconstruction of the images. In some practical situation, the projections outside the Tam-Danielsson window are available that indicate the data redundancy. In this work, we investigate image reconstruction on n-PI lines from data within n-PI window. We performed a preliminary numerical study, and the results in these studies shown that our algorithm can exactly reconstruct images from n-PI data.
