Complex extension of optical flow and its practical evaluation for undersampled dynamic MRI
Matthias J. Ehrhardt, Marco Mauritz
Reconstructing high-quality images from undersampled dynamic MRI data is a challenging task and important for the success of this imaging modality. To remedy the naturally occurrin…
Convergence of Poisson point processes and of optimal transport regularization with application in variational analysis of PET reconstruction
Marco Mauritz, Benedikt Wirth
Poisson distributed measurements in inverse problems often stem from Poisson point processes that are observed through discretized or finite-resolution detectors, one of the most p…
Motion simulation of radio-labeled cells in whole-body positron emission tomography
Nils Marquardt, Tobias Hengsbach, Marco Mauritz +2
Cell tracking is a subject of active research gathering great interest in medicine and biology. Positron emission tomography (PET) is well suited for tracking radio-labeled cells i…
A Bayesian model for dynamic mass reconstruction from PET listmode data
Marco Mauritz, Bernhard Schmitzer, Benedikt Wirth
Positron emission tomography (PET) is a classical imaging technique to reconstruct the mass distribution of a radioactive material. If the mass distribution is static, this essenti…
