Abstract
The method calculates a scatter estimate for annihilation photons in a subject having a distribution of attenuation. The method can be used for scatter correction of detection data from a positron emission tomographic scanner. The method uses the following steps: —select a first scatter point Sand a second scatter point S, —determine a first scatter probability for scattering of a photon at scatter point Sand a second scatter probability for scattering of a photon at scatter point S, —determine an integral of the attenuation over a line connecting Sand S, —multiply the integral and the scatter probabilities and use the product in the calculation of the scatter estimate.
