Random coincidence correction method in gamma camera system, e.g. for use in PET or SPECT; involves obtaining several artificial trigger signals to obtain assigned measure of random coincidences for coincidence data

摘要

The method involves obtaining coincidence data that are assigned to an object by using radiation detector. Several artificial trigger signals are produced and used to obtain and assign a measure of random coincidences for coincidence data. Independent claims are included for a method for using a gamma camera system including the correction method, a gamma camera imaging system, a nuclear imaging system and a method for obtaining a measure of random coincidences.
