We are investigating methods for computational scatter estimation for scatter correction in cone-beam computed tomography. We have developed an analytical method for estimating single scatter. The paper discusses our analytical method and its validation using Monte Carlo simulations. The paper extends previous results to include both Compton and Rayleigh single scatter interactions. The paper also discusses the potential for hybrid scatter estimation, in which empirical measurements of the total scatter signal in the collimator shadow may be used to augment computational single scatter estimates and thus account for multiple scatter.
