Patent ID: 8143585

Claim:
A method for reconstructing an image from a source (S) of photons, from interactions of photons emitted by this source, with a detector of a gamma-camera, positioned behind a collimator, comprising: reconstructing an image of the source (S) of photons, the method further comprising breaking down the detector into several pixels, and each pixel into several voxels, and further comprising, prior to the reconstruction step, the following steps: determining for each received photon, the voxel of the detector in which the photon has interacted, and counting for each voxel of the detector the number of photons having interacted in this voxel, defining for each voxel of the detector, a raw or differential statistical datum, a raw datum corresponding to the number of photons counted for the relevant voxel, a differential datum corresponding to a difference between numbers of counted photons, and wherein the reconstruction step is implemented from said statistical data.
