Method and apparatus for displaying body sounds and performing diagnosis based on body sound analysis
First Claim
1. A method comprising:
- receiving digital data corresponding to lung sounds detected during the inspiration and expiration of a patient having a chest by a plurality of transducers placed at various sites around the patient'"'"'s chest; and
generating, in response to the digital data, a display on a graphical user interface, the display having a display element in which the detected lung sounds from a plurality of transducers are plotted in a vertically stacked configuration,wherein the detected lung sounds from at least one transducer is plotted as a function of frequency over time.

Abstract
A lung sound diagnostic system for use in collecting, organizing and analyzing lung sounds associated with the inspiration(s) and expiration(s) of a patient. The system includes a plurality of transducers that may be placed at various sites around the patient'"'"'s chest. The microphones are coupled to signal processing circuitry and A/D converters which digitize the data and preferably provides the digital data to a computer station. A data collection and organization program, executing on the computer station, organizes and formats the data into a combination display for display or printing. The combinational display includes at least two display elements. In a first display element, the data is shown for both inspiration and expiration combined in a first time scale. In a second display element, the data for inspiration and expiration are shown individually in a second time scale that is time-expanded relative to the first time scale. The system may also include application programs for detecting and classifying abnormal sounds. The resulting information may be displayed in a variety of formats to facilitate diagnosis. Additionally, the system may include an analysis program for comparing selected criteria corresponding to the detected abnormal sounds with predefined thresholds in order to provide a likely diagnosis.
