Using NIR to monitor hemoglobin/myoglobin in human muscle is not new. NIR penetrates into muscle through skin and fat. Before reflectance spectra are correlated to oxygenated globin level in muscle, the spectra must be corrected for the reflectance in skin and fat. I read several papers and found the one way to correct skin and fat reflectance is to use two probes. One probe goes into muscle and the other goes into fat. Then the latter is substracted from the former to get the reflectance of muscle. I am not sure how that can be achieved technically. Different person has different thickness of fat layer on their muscle. How to automatically correct the fat reflectance remains a mystery to me. Can anyone shed some light into it? |
