In Coincident Doppler Broadening Spectroscopy(CDBS) the sum energy of the annihilation photons is checked to be 1022 keV, to validate the measurement of an undisturbed two- gamma electron- positron decay event. The events are stored in a two- dimensional acquisition matrix. A new algorithmis presented, which optimizes the extraction of the one- dimensional CDBS spectrum from this matrix by enhanced background suppression by the use of variable size bins.
