Abstract
A method and a circuit are provided for tuning or calibrating the gain of the radiation detectors of a radiation detection system. For each radiation detector tuning point the energy map status is measured in parallel. Thereby an energy response vector is obtained, which is multiplied with a predetermined deconvolution matrix. The deconvolution matrix is the inversion of a contribution matrix containing matrix elements C.sub.ij, each such matrix element C.sub.ij of said contribution matrix representing the relative contribution level of a radiation detector j of said detection system for a point radiation source placed at a location i. Thus a calculated gain vector is obtained with respect to which the gains of the radiation detectors are adjusted such that an ideal gain vector is obtained.
