Abstract
In this paper, an improved method of constructing FBP2D (3D) based variance map is introduced and implemented successfully. Accordingly, a quadratic version of distance driven back-projector (DD) compatible with variance reconstruction is developed to exploit fully the features of DD. As a result, the calculated variance is validated and shows an excellent match with ground truth.
