Patent ID: 8892184

Claim:
A magnetic resonance (MR)-positron emission tomography (PET) device dual modality system, comprising: a dual modality detector system including a PET detector device having a demodulator and counter and a plurality of PET detectors, and an MR detector device having a magnetic resonance (MR) receiver; conductors that are electrically connected to the plurality of PET detectors; MR coils positioned with respect to the conductors of the plurality of PET detectors such that said MR coils are subject to interference by spectral radiation from said conductors; a microprocessor and associated software which transmits modulated timing and frame synchronization signals to the PET detectors through said conductors, wherein the frame synchronization signal includes one or more missing framing signals, thereby reducing a spectral radiation of the conductors that causes interference to the MR receiver of the MR detector device, wherein the demodulator and counter detects the transmitted timing and frame synchronization signals at the PET detectors, and recovers the one or more missing framing signals.
