Frame averaging post-filter optimisation

摘要

A method to generate a nuclear medicine image reconstructed from an average of multiple subsets of acquired counts of a dataset, having an image quality characteristic aligned with that of a corresponding image obtained from a reconstruction of all counts of the dataset. A phantom data acquisition is used to determine an appropriate post-processing step necessary to align each image quality characteristic which provides a desired alignment of a given image quality characteristic. The determined post-processing step is applied to the combination of the multiple subset reconstruction.
