1. A system for detecting edema in a patient, the system comprising:
a light source configured to irradiate a patient's tissue with light;
a tunable filter configured to filter light reflected from the patient's tissue into one or more wavelength bands;
a detector configured to collect the tuned reflected light and generate data associated with the tuned reflected light;
a computer readable medium;
a processing device operably connected to the detector and the computer readable medium and configured to:
receive the data associated with the tuned reflected light that is separated light into one or more wavelength bands;
generate a visible image and a hyperspectral image,
calculate the intensity of the tuned reflected light,
compare the calculated intensity of the tuned reflected light against a control measurement;
fuse intensity data from the visible image and the hyperspectral image to spatially resolve individual pixels in the hyperspectral image,
determine whether the patient's tissue exhibits symptoms of edema,
access the computer readable medium, wherein the computer readable medium contains a look up table (LUT) that includes a plurality of voltages that, when applied to a filter, enable the filter to produce filtered light of a spectral shape associated with one or more tissue types related to edema, and
determine an edema score for the patient, wherein the edema score represents at least one of whether the patient has edema and a severity of the patient's edema; and
a display device operably connected to the processing device and configured to display images and information related to the detection of edema in the patient,
wherein the detector comprises one of an indium gallium arsenide detector and a focal plane array detector.
