A fully digital approach for MR compatible Time-of-Flight PET techniques
CERN, Meyrin, Switzerland Time-of-Flight PET (TOFPET) is likely to bring a significant improvement in PET image quality that could have a high impact in PET/MR acquisition and image reconstruction procedures. Silicon photomultipliers (SiPM) are known to be compatible with high magnetic fields. However, commercial SiPMs do not take advantage of their digital nature and are working in an analog m...
متن کاملPET/MR images acquired with a compact MR-compatible PET detector in a 7-T magnet.
PURPOSE To prospectively use compact avalanche photodiodes instead of photomultiplier tubes to integrate a positron emission tomographic (PET) detector and a 7-T magnetic resonance (MR) imager. MATERIALS AND METHODS All animal experiments were performed in accordance with the University of Tübingen guidelines and the German law for the protection of animals. A compact lutetium oxyorthosilicat...
متن کاملSimultaneous acquisition of multislice PET and MR images: initial results with a MR-compatible PET scanner.
UNLABELLED PET and MRI are powerful imaging techniques that are largely complementary in the information they provide. We have designed and built a MR-compatible PET scanner based on avalanche photodiode technology that allows simultaneous acquisition of PET and MR images in small animals. METHODS The PET scanner insert uses magnetic field-insensitive, position-sensitive avalanche photodiode ...

متن کاملEmission-based estimation of lung attenuation coefficients for attenuation correction in time-of-flight PET/MR.
In standard segmentation-based MRI-guided attenuation correction (MRAC) of PET data on hybrid PET/MRI systems, the inter/intra-patient variability of linear attenuation coefficients (LACs) is ignored owing to the assignment of a constant LAC to each tissue class. This can lead to PET quantification errors, especially in the lung regions. In this work, we aim to derive continuous and patient-spe...
