Improved MR to CT synthesis for PET/MR attenuation correction using Imitation Learning
Kerstin Kläser, Thomas Varsavsky, Pawel Markiewicz +6
The ability to synthesise Computed Tomography images - commonly known as pseudo CT, or pCT - from MRI input data is commonly assessed using an intensity-wise similarity, such as an…

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…
