Abstract (en)
[origin: WO2012098227A1] Method of determining a value for quantifying the deviation from the mean value of a distribution of the divergence in severity between an initial instant and a later instant subsequent to the initial instant, the severity depending on the contrast between zones receiving a treatment and zones receiving a vehicle, comprising steps in the course of which: at least one hyper-spectral image comprising at least one zone from among a diseased zone receiving the treatment, a healthy zone receiving the treatment, a diseased zone receiving the vehicle and a healthy zone receiving the vehicle is acquired, for at least one patient, at an initial instant and at at least one later instant subsequent to the initial instant, a decomposition of the hyper-spectral images into independent components is determined, a representative component maximizing the divergence between healthy zone and pathological zone is determined, for each image, from among the independent components, a representative component corrected as a function of the mean of the representative components is determined for each image, a value of the divergence in severity is determined as a function of the corrected representative components of the hyper-spectral images acquired, for each patient and for each measurement instant, and a value for quantifying the deviation from the mean value between a distribution of the divergence in severity at the initial instant and a distribution of the divergence in severity at a later instant subsequent to the initial instant is determined as a function of the value of the divergence in severity for each patient at the initial instant and at the later instant.
