SPECT image reconstruction methods and systems

摘要

Image reconstruction techniques for a medical imaging system are provided that include receiving pixel data from a gamma camera of an imaging system, and calculating a subsequent voxel value from the pixel data by subtracting an expected pixel value from a measured pixel value of the pixel data to produce a difference and correcting a previous voxel value by adding a weighted value of the difference to the previous voxel value. An imaging system is also provided.
