METHOD AND SYSTEM FOR SYNCHRONIZING POSITRON EMISSION TOMOGRAPHY (PET) DETECTOR MODULES

摘要

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.

1. A detector module for a positron emission tomography (PET) system, said detector module comprising:
an optical transceiver receiving an optical data stream from a PET processing system, the data stream including a pulse train carrying a command to generate sync/reset pulses; synchronization circuitry configured to:
simultaneously jitter clean the pulse train and one of:
count the pulses of the pulse train; and,monitor the pulse train for a missing pulse; and,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; and, an internal clock which receives the jitter clean sync/reset pulse.
