NON-INVASIVE METHOD FOR OBTAINING A PREDETERMINED FIELD OF ACOUSTIC WAVES IN A SUBSTANTIALLY HOMOGENEOUS ENVIRONMENT MASKED BY A BONE BARRIER, IMAGING METHOD, AND DEVICE FOR CARRYING OUT SAID METHODS

摘要

P Non-invasive method for obtaining an objective field of acoustic waves in the brain (19), by a network (17) of transducers positioned outside the skull (14), this method comprising a learning phase in during which, from a three-dimensional image giving the porosity of the skull at any point, elementary acoustic signals to be emitted by the transducers are determined by digital simulation in order to obtain the objective field of acoustic waves in the brain. After this learning phase, the transducer network is used to identify the relative position of the transducer network on the skull by ultrasound and to ensure precise positioning of the transducer network. /P
