| titleOfInvention | Method and non-invasive device for focusing sound waves |
| abstract | The present invention provides an image of a region to be observed in a dissipative heterogeneous medium (2, 3) in which an imaging network and a target network are formed around by acoustic transducers (T1-Tn, T′1-T′m). The present invention relates to a method of focusing a sound wave used for obtaining the above. In the learning step employed in this method, the pulse response from the medium is measured between each transducer (Ti) in the imaging network (5) and several transducers (Tj) in the target network (6), where To estimate the reference signal radiated by the imaging network transducer and generate a focused acoustic pulse in each transducer of the target network, and then cumulatively determine the radiated reference signal to determine the predetermined signal in the medium. The acoustic pulse is focused on the position of. The reference signal is stored and subsequently used to generate an acoustic image of the medium. |
