Videographic tomography. I. Reconstruction with parallel-beam projection data.
An approach to video-rate tomographic image reconstruction using standard filtered backpropagation is presented. Several methods of filtering are reported along with an optical system for backprojection. The focus is on reconstruction of data acquired in a parallel-beam geometry. The methods of implementing the filtering step are discussed, and the implementation of the backpropagation step is described. Results demonstrating the feasibility of the approach are presented.
