The present work explores a novel estimation method based on a Markov-Chain Monte-Carlo (MCMC) sampling in a Bayesian context. This new methodology allows the integration of prior knowledge on parameters that constrain the available solutions, which alleviates the identifia-bility problem. [...]

Abstract:In order to simplify the Point-Spread-Function (PSF) reconstruction framework, resolution modelling can be decoupled from the iterative reconstruction process by an additional data resampling step previous to reconstruction. We call the proposed algorithm RESampling between Projection spACEs (RESPACE). [...]

Abstract:Position emission tomography (PET) images usually suffer from low spatial resolution and signal-to-noise (SNR) ratio. The degradation of image resolution in PET is caused by detection process, e.g. [...]

Abstract:Most approaches of modelling neuroreceptor PET studies apply the cerebellum as reference area. Therefore, it is mandatory that the respective attenuation correction (AC) method for reconstructing the emission data is most appropriate regarding cerebellar areas. [...]

Abstract:Head movement is a major issue in dynamic PET imaging. A simultaneous MR-PET scanner is capable of acquiring both MR and PET data concurrently, which enables opportunities to use MR information for PET motion correction. [...]

This paper presents the conceptualization, design and simulation of a hybrid multi-frequency antenna system for Radio Frequency (RF) hyperthermia and Magnetic Resonance Imaging (MRI) applications with ultra-sharp hotspot. Two different bowtie antenna arrays have been designed, simulated and integrated. [...]

Ziel/Aim Currently, most radiomics studies on survival prediction in brain tumor patients are based on MRI only. The goal of our study was to evaluate multimodal radiomics derived from amino acid PET and MRI and clinical parameters for survival prediction in patients with newly diagnosed IDH wildtype glioblastoma.Methodik/Methods Sixty-three patients with newly diagnosed IDH wildtype glioblastoma were evaluated retrospectively. [...]

Topological quantum materials have attracted enormous attention since their discovery due to the observedanomalous transport properties, which originate due to the non-zero Berry curvature. Mn3Ge has gainedspecial attention because of its large anomalous Hall and Nernst effects that persist starting from Néeltemperature (365 K) down to 2 K [1, 2]. [...]

The Jülich High Brilliance neutron Source (HBS) is a High-Current Accelerator-driven Neutron Source(Hi-CANS). It is supposed to be Germany's future national neutron source replacing the high flux reactorFRM-2 in Garching close to Munich. [...]
