PET performance and MRI compatibility evaluation of a digital, ToF-capable PET/MRI insert equipped with clinical scintillators.
We evaluate the MR compatibility of the Hyperion-II(D) positron emission tomography (PET) insert, which allows simultaneous operation in a clinical magnetic resonance imaging (MRI) scanner. In contrast to previous investigations, this work aims at the evaluation of a clinical crystal configuration. An imaging-capable demonstrator with an axial field-of-view of 32 mm and a crystal-to-crystal spa...
متن کاملPET performance evaluation of a preclinical digital PET/MRI insert
Department of Physics of Molecular Imaging Systems, Institute for Experimental Molecular Imaging, RWTH Aachen University, Aachen, Germany In recent years, several groups have presented combined PET/MRI devices for clinical and preclinical research. Using new technologies like SiPMs, the performance of the systems improved over the years allowing a detailed exploration of the relatively new fiel...
متن کاملMR-compatibility study of a preclinical digital PET/MRI insert
Department of Physics of Molecular Imaging Systems, Institute for Experimental Molecular Imaging, RWTH Aachen University, Aachen, Germany The combination of PET and MRI into a hybrid device is challenging since both systems might interfere with each other. Therefore, the study of the MR-compatibility of such a combined device is crucial to understand and solve potential interference phenomena. ...
متن کاملPET/MRI insert using digital SiPMs: Investigation of MR-compatibility
In this work, we present an initial MR-compatibility study performed with the world's first preclinical PET/MR insert based on fully digital silicon photo multipliers (dSiPM). The PET insert allows simultaneous data acquisition of both imaging modalities and thus enables the true potential of hybrid PET/MRI. Since the PET insert has the potential to interfere with all of the MRI's subsystems (s...
متن کاملInitial PET performance evaluation of a preclinical insert for PET/MRI with digital SiPM technology
Hyperion-II(D) is a positron emission tomography (PET) insert which allows simultaneous operation in a clinical magnetic resonance imaging (MRI) scanner. To read out the scintillation light of the employed lutetium yttrium orthosilicate crystal arrays with a pitch of 1 mm and 12 mm in height, digital silicon photomultipliers (DPC 3200-22, Philips Digital Photon Counting) (DPC) are used. The bas...
