Iterative Image Reconstruction for Positron Emission Tomography Based on Detector Response Function Estimated from Point Source Measurements

The accuracy of the system model in an iterative reconstruction algorithm greatly affects the quality of reconstructed positron emission tomography (PET) images. For efficient computation in reconstruction, the system model in PET can be factored into a product of a geometric projection matrix and s...
