Patent ID: 8253116

Claim:
A method for locating at least N (N>1) absorber in a diffusing medium using at least one source of pulsed radiation capable of emitting radiation to excite this absorber, and at least one detector capable of measuring an emission signal emitted by this absorber comprising: illuminating the medium by a radiation source, detecting, by at least one detector, the emission signal emitted by this absorber, for at least one source-detector pair, performing a temporal distribution M sd (t) of the emission signal received by the detector, the diffusing medium being discretized into M voxels, each absorber occupying one voxel among the M voxels of the medium, according to a distribution m, and computing at least one basic parameter χ N i,m, which, for at least one of said temporal distributions M sd (t), combines at least one magnitude obtained from at least one moment of said distribution, and at least one estimation of this magnitude.
