Electronic Collimation
The use of coincidence with a pair of gammas giving a coincidence event in detectors 180 degrees apart in a PET scanner to define a line of response along which lies the location of the radiation emitting tracer. This differs from the use of slab collimators whose many holes define lines of response from a single gamma emission. (NCI Thesaurus)
