Abstract
An orthogonal projection sampling method is proposed in this paper for the reconstruction of incomplete data field by using the prior knowledge algorithm based on the modified algebra reconstruction technology (ART) in the optical computerized tomography (OCT). Experiments based to this method are studied. The satisfying reconstruction results are obtained with less sampling projection numbers and limited sampling angular range. The results indicate that orthogonal projection sampling can improve the precision in the reconstruction of incomplete data, and the precision reaches 10%. Β© 2006 Wiley Periodicals,Inc.

High-quality reconstruction of capacitance tomography data is of vital importance to ensure quantitative information from such systems. Several methods have been tested, such as linear back projection (LBP), representing a fast and crude method, and model-based reconstruction (MOR) which significant
## Abstract Diffusionβweighted MRI is a clinically useful technique, but its utility is compromised by high sensitivity to patient motion. Use of radialβscan data acquisition and projection reconstruction, rather than the conventional Fourier imaging method, can substantially reduce the sensitivity
