PET Rapid Image Reconstruction Challenge (PETRIC)
Casper da Costa-Luis, Matthias J. Ehrhardt, Christoph Kolbitsch +4
Introduction: We describe the foundation of PETRIC, an image reconstruction challenge to minimise the computational runtime of related algorithms for Positron Emission Tomography (…
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…
Faster PET Reconstruction with Non-Smooth Priors by Randomization and Preconditioning
Matthias J. Ehrhardt, Pawel Markiewicz, Carola-Bibiane Schönlieb
Uncompressed clinical data from modern positron emission tomography (PET) scanners are very large, exceeding 350 million data points (projection bins). The last decades have seen t…
