Implementation and validation of the advanced variance estimation technique using CT projection data

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.
