Abstract :
The measurement of total hemoglobin concentration is currently invasive and time consuming. The optoacoustic technique may provide accurate and noninvasive measurements of total hemoglobin concentration by probing blood vessels. We studied the influence of blood vessel diameter and lateral displacement of the optoacoustic probe on accuracy of total hemoglobin concentration measurements with this technique.
