A method of beamforming datasets from a tomographic detection system. The system comprises scintillation detectors that are arranged in D detector pairs, D1, wherein the detectors are adapted to count radiation hits. According to the method in one aspect, a tomographic dataset is received for each detector pair coordinates (.sub.d, p.sub.d) of a detector pair d of the D detector pairs, so as to obtain a plurality of tomographic datasets. Each of said datasets is associated with respective detector pair coordinates (.sub.d, p.sub.d). Then, for each point y of interest, the received datasets are coherently combined by weighting the datasets according to respective beamforming weights .sub.d(y)=(.sub.d, p.sub.d; y), based on said respective detector pair coordinates (.sub.d, p.sub.d) and coordinates of said each pointy of interest. This way, a signal focusing on said each pointy is obtained. Related tomographic detection systems and computer program products may be also presented.
