Abstract

We recently demonstrated that the view angles of tomographic projections were uniquely determined by the projection data alone for almost all objects, given enough projections. In this work, we present results on the stability of the solution, as well as bounds on the variance of Convolution Back Projection (CBP) based reconstructions. To demonstrate that the problem can be feasibly solved in the presence of noise, we present a maximum likelihood estimator with a heuristic initialization algorithm which estimates the orientation of each projection.
