Abstract
Systems and methods for spatial optimization of blood measurements in tissue are disclosed. Exemplary methods include: measuring a first Raman signal from the tissue with a probe at a first position; calculating a first percentage of a blood component in the first Raman signal; moving the probe a predetermined distance to a second position; measuring a second Raman signal with the probe at the second position; calculating a second percentage of the blood component in the second Raman signal; moving the probe the predetermined distance to a third position when the second percentage is greater than the first percentage; measuring a third Raman signal with the probe at the third position; calculating a third percentage of the blood component in the third Raman signal; moving the probe to the second position when the third percentage is less than the second percentage; and taking spectral measurements from the second position.
