A method of processing an image data set of a 3D PET scanner to correct for scattered coincidence events, as well as a 3D PET scanner, are disclosed. The method of processing the image data set includes providing an image data set including a first plurality of data subsets respectively corresponding to a plurality of native slices. The method additionally includes axially downsampling the first plurality of data subsets to generate a second plurality of data subsets respectively corresponding to a plurality of super-slices. The method further includes calculating scatter in the second plurality of data subsets by way of a model-based scatter correction algorithm.
