Abstract:
1. A method for optimising the focussing of waves in a region of interest of a in a patient, with the waves being emitted by a network of N sources to the region through an aberration-inducing element that introduces an initially indeterminate phase shift φ n (1≦n≦N), with the method using M−1 successive modifications of the emitted wave, each giving rise to a perturbation, the M perturbations are measured, and these measurements are used to deduce optimal focussing characteristics, including the following steps: a) emission, via the network of N sources, of waves A b) M−1 (M>1) modifications of the spatial phase α c) measurement of at least one perturbation I d) deduction, from the perturbation measurements I
