Method and systms for regional assessment of pulmonary function

摘要

A method and system for regional assessment in two or more regions of an individual's lungs. The system includes a plurality of transducers configured to be fixed over the thorax. Each transducer generates a signal P(x_i,t) indicative of pressure waves at the location of the transducer. The transducers are divided into subsets, where each subset overlies a specific region of the two or more regions. An energy assessment signal is calculated from each of the signals P(x_i,t). For each region, an assessment of the region is calculated from the energy assessment signals of the region.
