Patent ID: 11864880
Assignee: THE UNIVERSITY OF QUEENSLAND
Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 0:
1. A method for diagnosing one or more diseases of the respiratory tract for a patient, the method comprising:
processing cough sounds acquired from a patient to produce cough sound feature signals representing one or more cough sound features from the cough segments;
obtaining one or more disease signatures based on the cough sound feature signals; and
classifying the one or more disease signatures to deem the cough segments as indicative of one or more of said diseases;
wherein the obtaining of the one or more disease signatures based on the cough sound feature signals includes applying the cough sound features to each of a plurality of pre-trained disease signature decision machines, at least one of the pre-trained disease signature decision machines having been pre-trained to classify the cough sound features as corresponding to either a particular disease or to a non-disease state, and at least one other of the pre-trained disease signature decision machines having been pre-trained to classify the cough sound features as corresponding to a first particular disease or a second particular disease different from the first particular disease,
wherein a plurality of disease signatures are obtained, each said disease signature being generated as a respective axis having values varying continuously between 0 and 1 and defining a respective space for distinguishing between two different diagnoses,
wherein a response is provided for the patient along each of the axes, and
wherein the responses for the axes are provided for the classifying.
