CA 2630936

The invention provides a system and method for regional assessment of lung physiology. The system includes a plurality of sound transducers configured to be fixed on a surface of the individual over the thorax. A processor is configured to receive signals generated by the transducers and to determine from the signals a value of a parameter in each of one or more regions of the lungs. The method of the invention includes obtaining signals indicative of pressure waves at locations over the thorax; and determining from the signals a value of a parameter in each of the regions of the lungs.

L'invention concerne un système et une méthode pour évaluer la physiologie pulmonaire régionale. Le système inclut une pluralité de transducteurs de son configurés pour être fixés sur une surface du thorax d~un individu. Un processeur est configuré pour recevoir des signaux produits par lesdits transducteurs et pour déterminer une valeur d'un paramètre dans une ou plusieurs régions des poumons à partir des signaux. La méthode de l'invention inclut les étapes consistant à obtenir des signaux indicatifs d'ondes de pression en des lieux sur le thorax ; et à déterminer à partir des signaux une valeur d'un paramètre dans chacune des régions des poumons.
