Beamforming for tomographic detection systems

A method of beamforming datasets from a tomographic detection system. The system comprises scintillation detectors that are arranged in D detector pairs, D≥1, 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 (θd, pd) 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 (θd, pd). Then, for each point y of interest, the received datasets are coherently combined by weighting the datasets according to respective beamforming weights d(y)=ω(θd, pd; y), based on said respective detector pair coordinates (θd, pd) and coordinates of said each point y of interest. This way, a signal focusing on said each point y is obtained. Related tomographic detection systems and computer program products may be also presented.
