The goal is to detected the prompt-gamma (PG) radiation which emerges from the patient, and estimate the underlying activation distribution by using tomographic reconstruction algorithms. The reconstructed CC images are often affected by high levels of statistical noise and other artefacts. With the aim of improving the reconstructed images, here we study various approaches able to exploit a-priori information from a beam-tagging hodoscope. The latter provides an estimation about the beam spread and its direction, so that this information can be used before or during the reconstruction in different ways, e.g. to restrict the volume-of-response assigned to each event, or to design a novel penalty function for regularized image reconstruction. We have implemented several approaches using Monte Carlo simulated data. In particular, our penalized reconstruction led to a significant improvement of the image quality. The estimated distal edge was well resolved for all tested scenarios.}, author = {Kohlhase, Nadja and Stille, Maik and Bolke, Andreas and Zvolský, Milan and Rafecas, Magdalena}, booktitle = {2020 {IEEE} Nuclear Science Symposium and Medical Imaging Conference ({NSS}/{MIC})}, keywords = {BolkeAndreas CC Compton IMT KohlhaseNadja NucI NucIRangeVerification RafecasMagdalena Simulation StilleMaik ZvolskyMilan}, month = {oct}, pages = {1-4}, title = {Compton Camera Image Reconstruction with A-Priori Information from a Beam Tagging Hodoscope}, year = 2020 }

Data of projections passing through objects of high density, such as metal implants, are dominated by noise and are highly affected by beam hardening and scatter. Reconstructed images become less diagnostically conclusive because of pronounced artifacts that manifest as dark and bright streaks. A new reconstruction algorithm is proposed with the aim to reduce these artifacts by incorporating information about shape and known attenuation coefficients of a metal implant. Image reconstruction is considered as a variational optimization problem. The afore-mentioned prior knowledge is introduced in terms of equality constraints. An augmented Lagrangian approach is adapted in order to minimize the associated log-likelihood function for transmission CT. During iterations, temporally appearing artifacts are reduced with a bilateral filter and new projection values are calculated, which are used later on for the reconstruction. A detailed evaluation in cooperation with radiologists is performed on software and hardware phantoms, as well as on clinically relevant patient data of subjects with various metal implants. Results show that the proposed reconstruction algorithm is able to outperform contemporary metal artifact reduction methods such as normalized metal artifact reduction.}, author = {Stille, M. and Kleine, M. and Hagele, J. and Barkhausen, J. and Buzug, T.M.}, journal = {IEEE Transactions on Medical Imaging}, keywords = {BuzugThorsten CT IMT MetalArtefactReduction StilleMaik}, month = {jan}, number = 1, pages = {158-173}, title = {Augmented Likelihood Image Reconstruction}, volume = 35, year = 2016 }

  @article{Stille2013b, abstract = {Abstract To validate and add value to non-invasive imaging techniques, the corresponding histology is required to establish biological correlates. We present an efficient, semi-automated image-processing pipeline that uses immunohistochemically stained sections to reconstruct a 3D brain volume from 2D histological images before registering these with the corresponding 3D in vivo magnetic resonance images (MRI). A multistep registration procedure that first aligns the “global” volume by using the centre of mass and then applies a rigid and affine alignment based on signal intensities is described. This technique was applied to a training set of three rat brain volumes before being validated on three normal brains. Application of the approach to register “abnormal” images from a rat model of stroke allowed the neurobiological correlates of the variations in the hyper-intense \{MRI\} signal intensity caused by infarction to be investigated. For evaluation, the corresponding anatomical landmarks in \{MR\} and histology were defined to measure the registration accuracy. A registration error of 0.249 mm (approximately one in-plane voxel dimension) was evident in healthy rat brains and of 0.323 mm in a rodent model of stroke. The proposed reconstruction and registration pipeline allowed for the precise analysis of non-invasive \{MRI\} and corresponding microstructural histological features in 3D. We were thus able to interrogate histology to deduce the cause of \{MRI\} signal variations in the lesion cavity and the peri-infarct area.}, author = {Stille, Maik and Smith, Edward J. and Crum, William R. and Modo, Michel}, journal = {Journal of Neuroscience Methods}, keywords = {StilleMaik}, number = 1, pages = {27-40}, title = {3D reconstruction of 2D fluorescence histology images and registration with in vivo \{MR\} images: Application in a rodent stroke model}, volume = 219, year = 2013 }
