An MR-compatible PET detector module featuring a silicon photomultiplier coupled to a dual-layer LYSO scintillator crystal array and using an HDMI cable for supplying power and bias as well as transmitting analog signals was tested in a 7 T Bruker MRI. Performance of the PET detector was evaluated inside the MRI as was performance of the MRI with the PET detector present and operating. Given the limited interactions between the operating PET detector module and MRI, the current PET detector design appears to be a viable first step in creating an MR-compatible full-ring PET system.
