Abstract: A method for improved cardiac monitoring is disclosed. The method includes receiving image data from an image sensor configured for monitoring edema in a patient. Additional data is received from one or more additional sensors configured to monitor one or more factors related to cardiac activity of the patient. The received image data is fused with the received additional data from the one or more additional sensors to generate fused data set. A cardiac condition for the patient is determined based on the fused data set. A cardiac monitoring computing device and non-transitory medium are also disclosed.

Abstract: Raman spectroscopy data is collected using a Spatial Heterodyne Spectrometer and processed in order to reduce signal noise. The processing of the Raman spectroscopy data includes segmenting generating an interferogram from the Raman spectroscopy data, segmenting the interferogram, determining an estimate of power spectrum density, and averaging the estimates of power spectrum density for each segment to provide an output spectrum. The output spectrum has greatly reduced variance of the individual power measurements, and allows the length of segments to be optimized to balance noise reduction operations and the loss of frequency resolution.
