Method and apparatus for displaying body sounds and performing diagnosis based on body sound analysis
First Claim
1. A method for collecting, organizing and displaying lung sound information during the inspiration and expiration of a patient as detected by a plurality of transducers placed at various sites around the patient'"'"'s chest, the method comprising the steps of:
- receiving digital data corresponding to the lung sounds detected by the transducers; 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 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.

6. A diagnostic system for use with a patient, the diagnostic system comprising:
-
a plurality of transducers for placement at various sites around the patient, the transducers configured to generate signals that are responsive to sounds from within the patient;
a sound generator configured to input a sound to the patient;
a data collector and organizer configured to receive the signals generated by the plurality of transducers in response to the input sound; and
a display screen operatively coupled to the data collector and organizer, wherein the date collector and organizer displays the signals received by the plurality of transducers in response to the input sound on the display screen. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

14. A diagnostic system for use with a patient, the diagnostic system comprising:
-
a plurality of transducers for placement at various sites around the patient, the transducers configured to generate signals that are responsive to sounds from within the patient;
a sound localizer configured to receive the signals generated by the plurality of transducers for a given sound and to calculate a set of three dimensional coordinates corresponding to an origin of the given sound; and
a display screen operatively coupled to the sound localizer, wherein the sound localizer generates a three-dimensional representation of the patient that includes one or more markings for the given sound, the one or more markings appearing on the three-dimensional representation in relation to the calculated coordinates.
