Abstract:
1. A system for analyzing mechanical waveforms to identify a given pathology comprising: an instrument for acquiring a mechanical waveform from a subject during a functional cycle; a signal processor connected to receive the mechanical waveform from the instrument and normalize the mechanical waveform over at least one portion of functional cycle; a neural network coupled to the signal processor to receive an entirety of the mechanical waveform as a normalized mechanical waveform after processing by the signal processor and process the normalized mechanical waveform based on a plurality of weights selected by a training process that relates mechanical waveforms to a diagnostic outcome related to the given pathology, the neural network being operable to generate at least one metric indicating a degree of relation between the normalized mechanical waveform and the diagnostic outcome; a diagnostic interpretation module receiving the at least one metric from the neural network and classifying the mechanical waveform as at least one of indicative of the given pathology and not indicative of the given pathology based on a comparison of the at least one metric to at least one probability distribution of a likelihood of the given pathology; and wherein the mechanical waveform includes an echocardiographic waveform and the given pathology includes ischemic myocardium.
