Abstract
A method and apparatus by which lung deceases are identified uses computer analysis of sound signals that are picked up from various locations on the chest walls of a subject by a modified stethoscope. The modification includes a small microphone in one of the hoses of the stethoscope. Signals from the microphone are input to a computer such as a personal computer or PC for processing. The computer extracts from these signals features which are dominant for particular lung diseases. A classifier classifies these features, determines if the lungs are diseased, and identifies the disease.

11. An apparatus for identifying a lung disease in a subject, the lung disease producing lung sounds that are characteristic of the lung disease, the apparatus comprising:
- a stethoscope for acquiring the lung sounds from the subject;
a transducer operatively connected to the stethoscope for converting the lung sounds to a signal; and
a computer-based analyzer for analyzing the signal to identify the lung disease. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
