Fast PET Reconstruction with Variance Reduction and Prior-Aware Preconditioning

Matthias J. Ehrhardt, Zeljko Kereta, Georg Schramm

We investigate subset-based optimization methods for positron emission tomography (PET) image reconstruction incorporating a regularizing prior. PET reconstruction methods that use…
