MADPET4 (Munich Avalanche Diode PET 4) is a small animal PET insert for a 7 T MRI scanner, which has two offset layers of scintillation crystals, individually read out by silicon photomultipliers (SiPMs). To reduce the interference between the PET insert and the MRI system, high-gain SiPMs were used and the SiPM charge was transferred to outside the MRI scanner using 1.5 m coaxial cables. In...

The aim of the SAFIR collaboration is the construction of a positron emission tomography (PET) insert for a preclinical magnetic resonance imaging (MRI) device. The device will be able to handle high source activities and the target time for one PET image acquisition is 5 s. The mechanical design is very challenging, because the inner diameter of the MRI scanner’s bore limits the diameter of...

We present the conclusive measurements of the characterization of a preclinical SPECT insert compatible with standard MR scanners and targeting neuro-oncology. The instrument is composed of a static gantry of 10 gamma cameras based on arrays of SiPMs coupled to a 50mm by 50mm CiI(Tl) continuous scintillator. Each module features a 36-channel readout ASIC, an optimized MRI-compatible layout,...

Two different depth-of-interaction (DOI) encoding detector designs were studied for the SAFIR (Small Animal Fast Insert for mRi) PET system to improve spatial resolution in the axial direction. One is a two-layer DOI detector with two layers of crystals stacked with an offset of half crystal pitch. The other is a single-layer DOI detector using triangular shaped ESR reflectors between...

Powerful new high-resolution imaging tools such as optical whole body imaging (FOBI), magnetic resonance imaging (MRI) could thus nowadays enable very good anatomical detail fusion to functional image data (positron emission tomography (PET) and single photon emission computed tomography (SPECT)). With the availability of these novel multimodal imaging devices the demand for innovative...
