Bowsher prior
WebJan 1, 2024 · In this work, we demonstrate that anatomically-guided PET reconstruction using the asymmetric Bowsher prior can be well-approximated by a purely shift-invariant … WebIn this study, we are dealing with some challenges of the Bowsher prior in order to modify it to a more au- tomatic and stable technique. Our aim is to achieve enhanced edge-preserving characteristics of the recon- structed emission images by introducing an automated approach for choosing more similar neighbouring voxels on anatomical images.

The two latter priors do not rely on an explicit segmentation, which makes them more generally applicable than a segmentation-based prior. All three priors produced a compromise between noise and …
WebWe propose a forward-backward splitting algorithm to integrate deep learning into maximum-a-posteriori (MAP) positron emission tomography (PET) image reconstruction. The MAP reconstruction is split into regularization, expectation-maximization (EM), and a weighted fusion. For regularization, the use of either a Bowsher prior (using Markov-random … WebBowsher et al [5] proposed an anatomical prior avoiding use of segmented anatomical information. This prior (referred to as the Bowsher prior) encourages smoothing over …
