Abstract
Devices and methods are provided for assessing the condition of tissue, in particular to diagnose the location and stage of diseases such as emphysema. In one device or method according to the invention, sound is introduced into lung tissue. A portion of the sound is detected after it has passed through a portion of the lung. A sound-propagation parameter is determined by comparing a property of the introduced sound and a property of the detected sound. A region of examination of the tissue is identified, based in part on either a property of the component that introduces the sound or a property of the component that detects the sound. The condition of the tissue is assessed in the region of examination, based in part on the sound-propagation parameter.
