Abstract
Timing is determined in positron emission tomography (PET). Two or more different types of timing detection are used for each event. The difference in time from the different types of timing detection may indicate whether or not an error has occurred. An average difference or other typical offset difference may be used to correct the error. During pile up, the difference information may be used to create a missing time, such as using an average difference between second derivative and constant fraction discrimination as an offset to determine constant fraction timing from second derivative timing.
