DEVICE, SYSTEM AND METHOD FOR DETECTION OF FLUID ACCUMULATION
First Claim
1. A method of detecting a level of fluid accumulation in an internal organ of a subject, comprising:
- providing at least one classifier trained to distinguish between two or more levels of fluid accumulation;
acquiring an audio signal generated by said internal organ; and
processing said audio signal by;
performing feature extraction to generate at least one feature vector from the audio signal;
assigning a fluid level from the two or more levels to the audio signal by passing the at least one feature vector to the at least one classifier.

Abstract
A method of detecting a level of fluid accumulation in an internal organ of a subject is proposed, as well as a system for carrying out the method. The method comprises: providing at least one classifier trained to distinguish between two or more levels of fluid accumulation; acquiring an audio signal (110) generated by said internal organ; and processing, using at least one processor (134), said audio signal (110) by: performing feature extraction to generate at least one feature vector from the audio signal; and assigning a fluid level from the two or more levels to the audio signal by passing the at least one feature vector to the at least one classifier.

15. A system for detecting a level of fluid accumulation in an internal organ of a subject, comprising:
-
at least one sensor positionable on the subject to measure an audio signal from said internal organ; a memory configured to store data representing the audio signal; and at least one processor in communication with the memory and being configured to; retrieve, from said memory, data representing at least one classifier trained to distinguish between two or more levels of fluid accumulation; process said audio signal by performing feature extraction to generate at least one feature vector from the audio signal; and assign a fluid level from the two or more levels to the audio signal by passing the at least one feature vector to the at least one classifier.

16. A system for detecting a level of fluid accumulation in an internal organ of a subject, comprising:
-
at least one sensor positionable on the subject to measure an audio signal from said internal organ; and at least one processor configured to perform feature extraction to generate at least one feature vector from the audio signal; and assign to the audio signal a fluid level which is one of a set of two or more levels by passing the at least one feature vector to at least one classifier trained to distinguish between the two or more levels of fluid accumulation.
