  • Publication number: 20210022623
    Abstract: Systems and methods are disclosed for determining physiological information in a subject. The system includes; a light source positionable along a first location outside of the subject; a photo-sensitive detector positionable along a second location outside of the subject and configured to detect scattered light and generate a signal; a processor having a program and a memory, wherein the processor is operably coupled to the detector and configured to receive and store the signals generated over a period of time; wherein the processor is programmed to derive contrast metrics from the stored signals, calculate a waveform from the contrast metrics, decompose the waveform into basis functions and respective amplitudes, and compare the basis function amplitudes to determine the physiological information.
    Type: Application
