Abstract

X-ray scatter correction is an open problem in the research of cone beam CT (CBCT). In this paper, using semitransparent beam stop array (BSA) introduced recently1, an improved BSA method2 is proposed. A simple iterative correction algorithm is developed based on the knowledge that mostly primary varies continuously. With the proposed method, scatter correction could be accomplished without extra scan. Experiments are carried out based on the Monte Carlo (MC) simulation (EGSnrc), the mean square error (MSE) is reduced from 50.71% (with no correction) to 2.54%, and there is no visible negative impact introduced by the correction.
