Abstract
A cylinder () of radiation detectors () in a diagnostic imaging apparatus detects radiation pairs with corresponding electronic detector channels () which have non-uniform time-varying temporal delays. A plurality of calibration radiation sources () that concurrently emit radiation pairs is mounted at known positions inside of the cylinder. A temporal correction processor () uses the known positions of the calibration sources to determine errors in the relative detection times of radiation pairs from the calibration sources and uses the determined errors to generate corrections for the relative detection times of radiation pairs from radiopharmaceuticals injected in an imaged subject.
