Claim 0:
1. A method comprising:
obtaining, by one or more processors, data acquired from a measurement of one or more biopotential signals of a subject, wherein the acquired data comprises high-frequency time series data having a frequency component greater than about 1 kHz and less than about 10 kHz;
generating, by the one or more processors, one or more phase space volumetric objects based on the acquired data, wherein at least one of the one or more phase space volumetric objects comprises a plurality of faces and a plurality of vertices, wherein the plurality of vertices are determined by subtracting data points of a base-line raw channel data set of the acquired data with corresponding data points of a modeled channel data set, wherein the modeled channel data set is generated from a model-derived reconstruction operation of the acquired data to generate low-energy subspace parameters; and
determining, by the one or more processors, using a machine-learned classifier, (i) a parameter associated with a presence, absence, or degree of significant coronary artery disease or (ii) one or more coronary physiological parameters of the subject selected from the group consisting of a fractional flow reserve estimation, a stenosis value, and a myocardial ischemia estimation, based on the generated phase space volumetric object.
