TIME-OF-FLIGHT POSITRON EMISSION TOMOGRAPHY USING CERENKOV RADIATION

摘要

The invention relates to a method of time-of-flight positron emission tomography of an object comprising a positron emitter located in a target region, said target region being spatially surrounded by an array of detector elements, the method comprising the steps of using for the detector elements a material capable of generating a first event and a second event pursuant to a passage of a 511 keV photoelectron therein; detecting in the detector element the first event for timing the time-of-flight measurement; detecting in the detector element the second event for carrying out energy measurement. The invention further relates to a PET apparatus 30, wherein a detector element is capable of generating Cerenkov light and scintillation light pursuant to such passage. The invention further relates to a computer program product 34.
