Claim 8:
9. A method for measuring tissue properties in a subject, comprising the steps of:
a) illuminating a tissue of interest in the subject with a non-isosbestic wavelength emitted from the plurality of excitation light sources comprising the medical device of claim 1;
b) measuring a reflected non-isosbestic wavelength via the image sensor comprising the device;
c) illuminating the tissue of interest with an isosbestic wavelength;
d) measuring a reflected isosbestic wavelength;
e) determining a ratiometric image sensor measurement of the reflected non-isosbestic wavelength to the reflected isosbestic wavelength via the algorithm comprising the medical device;
f) correlating the ratiometric image sensor measurement with at least one tissue property of the tissue of interest; and
g) repeating steps a) to f) at least once with another non-isosbestic wavelength and the isobestic wavelength.
