Abstract: A method of correcting a timing signal that represents an arrival time of a photon at a positron emission tomography (PET) detector includes receiving a timing signal that represents an arrival time of a photon at a PET detector, receiving an energy signal indicative of an energy of the photon, calculating a timing correction using the energy signal, modifying the timing signal using the timing correction, and generating an image of an object using the modified timing signal. A system and non-transitory computer readable medium are also described herein.

Abstract: The present invention, in one form, is a communication system for transmitting high-speed data across an imaging system slip-ring. In one embodiment, the communication system includes a transmitter and a receiver. The transmitter generates encoded serial data that is transmitted across the slip-ring 1 bit at a time to the receiver. The encoded data includes command codes, message blocks having CRC data, and SYNC data. Using the commands codes, the receiver decodes the data into byte data. The receiver utilizes the CRC data to detect and correct errors in the transmitted data and the SYNC data to synchronize the receiver with the transmitter.
