SYSTEM AND METHOD FOR SPECTRAL-BASED DISEASE DETECTION

Abstract

A system includes a light source that emits broadband light through a test cassette containing a fluid. A spectrometer disperses the broadband light, after passing through the test cassette, onto a plurality of pixel detectors of a detector array. A digitizer reads an array of raw spectral values from the detector array. A signal processing circuit deconvolves, based on a spectral response of each of the plurality of pixel detectors, the array of raw spectral values to generate an array of deconvolved spectral values; feeds the array of deconvolved spectral values into a trained machine-learning model to obtain an indication of the presence of one or more constituents in the fluid; and outputs the indication. The fluid may be human saliva or another biological fluid obtained from a patient. The indication may be used to diagnose the patient with a disease or condition.
