Stochastic EM methods with Variance Reduction for Penalised PET Reconstructions
Zeljko Kereta, Robert Twyman, Simon Arridge +2
Expectation-maximization (EM) is a popular and well-established method for image reconstruction in positron emission tomography (PET) but it often suffers from slow convergence. Or…
Penalized PET/CT Reconstruction Algorithms with Automatic Realignment for Anatomical Priors
Yu-Jung Tsai, Alexandre Bousse, Simon Arridge +3
Two algorithms for solving misalignment issues in penalized PET/CT reconstruction using anatomical priors are proposed. Both approaches are based on a recently published joint moti…
Deep Boosted Regression for MR to CT Synthesis
Kerstin Kläser, Pawel Markiewicz, Marta Ranzini +7
Attenuation correction is an essential requirement of positron emission tomography (PET) image reconstruction to allow for accurate quantification. However, attenuation correction…
