NON-INVASIVE METHOD OF OBTAINING A PRE-DETERMINED SOUNDWAVE FIELD IN A SUBSTANTIALLY HOMOGENEOUS MEDIUM MASKED BY A BONE BARRIER FOR IMAGING OR HYPERTHERMIA TREATMENT, A METHOD OF MEDICAL IMAGING BY ECHOGRAPHY AND APPARATUS FOR IMPLEMENTING THE METHODS

摘要

The invention relates to a non-invasive method of obtaining an acoustic wave field in the brain (19) using a network (17) transducers, which is positioned outside the skull (14). The inventive method comprises an information acquisition phase, whereby a three-dimensional image of the porosity of the skull at every point is used to determine, by means of digital simulation, the elementary acoustic signals to be emitted by the transducers in order to obtain the acoustic wave field in the brain. After said information acquisition phase, the transducer network is used to locate, by means of ultrasonography, the relative position of the transducer network on the skull and to provide a precise position for said network.
