Practical Intrinsic-Error Bounds for X-Ray Computed Tomography

Abstract

Images produced by x-ray computed tomography contain intrinsic error due to the limited spatial resolution of the technique. Two bounds on the mean intrinsic error over a specified region are determined, given only minimal information about the object, namely its phase composition. One bound is an upper bound applicable to a class of image reconstruction algorithms; the other is a lower bound on worst-case error applicable to any algorithm. A commonly used data collection mode is found to be subject to large intrinsic error, and a much better substitute isidentified.
