Abstract: A detector module (50) for a positron emission tomography (PET) system (10) includes an optical transceiver (66) receiving an optical data stream from a PET processing system (48). The data stream includes a pulse train carrying a command to generate sync/reset pulses. The system (10) further includes synchronization circuitry (70) configured to simultaneously jitter clean the pulse train and one of: 1) count the pulses of the pulse train; and 2) monitor the pulse train for a missing pulse. The synchronization circuitry (70) is further configured to, in response to counting a predetermined number of pulses or detecting the missing pulse, extract a jitter clean pulse from the pulse train to generate a jitter clean sync/reset pulse. The system (10) further includes an internal clock (64) which receives the jitter clean sync/reset pulse.

Abstract: The present invention relates to a method and a system for reducing interference between a non-MR imaging system (e.g. a PET imaging scanner) and an MR imaging system. The method comprises receiving at least a signal indicative of the MR RF signal detection period, and in response to the received signal, setting the state of at least a portion of the non-MR imaging system to an inactive state during at least a portion of the MR RF signal detection period.

Abstract: A PET or SPECT radiation detector module (50) includes an array of detectors (54, 58) and their associated processing circuitry are connected by a flexible cable having releasable connectors. A method of mounting and dismounting includes mounting a radiation detector array in a support structure in a diagnostic scanner, connecting one end of a flexible connector to the detector array, and connecting the other end of the flexible connector to its associated circuitry.
