Curriculum Vitae

REBECCA KANTOREK grew up in Bad Neuenahr-Ahrweiler, Germany. In 2020 she received her bachelor's degree in Medical Engineering from Koblenz University of Applied Sciences, Germany. She received her M.Sc. in Medical Engineering from the University of Lübeck, Germany, in 2025. During her master thesis at the University of Lübeck she worked on the implementation of a decay correction for a PET prototype for the imaging of living adult zebrafish.

@article{11511820, abstract = {Inter-crystal scattering (ICS) in Positron Emission Tomography (PET) is commonly regarded as a degradation effect that might compromise the image spatial resolution. In parallel, the inclusion of ICS events has also been recognized as a potential approach to increase PET sensitivity, which could be especially beneficial in scenarios where the latter is a limiting factor, such as very small animal imaging. Several methods for the recovery of ICS events have been proposed, many of which aim to locate the first interaction, i.e., the Compton scattering site, usually limited by their success rate, computational burden or data and training dependency. Conversely, this work proposes a physics-based model for ICS events, leading to analytical expressions of the sensitivity image and the system matrix (required by statistical reconstruction algorithms), without the need to identify the original line of response. After validating the model, the work shows how ICS events can be integrated into a joint image reconstruction algorithm (based on list-mode MLEM) together with conventional PET events, for which dedicated analytical models are also developed. To assess the performance of the proposed approach, Monte-Carlo simulated and experimental data of an image quality phantom were obtained with the MERMAID small-fish PET scanner prototype. Both simulation and experimental results indicate that, while slightly decreasing the recovery coefficient values, the inclusion of ICS clearly reduces statistical noise and improves uniformity.}, author = {Roser, Jorge and Vo, Hong Phuc and Kantorek, Rebecca and Seeger, Steven and Rafecas, Magdalena}, journal = {IEEE Transactions on Radiation and Plasma Medical Sciences}, keywords = {pet}, pages = {1-1}, title = {Inclusion of Inter-crystal Scattering in PET: Analytical Models and Dedicated Reconstruction}, year = 2026 }
