Abstract
A radiation detector module () for use in a time-of-flight positron emission tomography (TOF-PET) scanner () generates a trigger signal indicative of a detected radiation event. A timing circuit () including a first time-to-digital converter (TDC) () and a second TDC () is configured to output a corrected timestamp for the detected radiation event based on a first timestamp determined by the first TDC () and a second timestamp determined by the second TDC (). The first TDC is synchronized to a first reference clock signal () and the second TDC is synchronized to a second reference clock signal (), the first and second reference clock signals being asynchronous.
