Abstract
Cerebral hemodynamics and tissue morphology is important for evaluating brain function and tissue viability in neurosurgery as well as in the diagnosis of several neurological disorders. Diffuse reflectance spectroscopy is one of the most promising methods for evaluating the cerebral hemodynamics and regional cerebral oxygen saturation of in vivo brain tissue. Diffuse reflectance spectroscopy based on the measurement of CW light can be simply achieved with an incandescent white light source, inexpensive optical components, and a spectrometer. Several imaging methods based on diffuse reflectance obtained from the exposed in vivo brain tissue have been used to acquire the spatiotemporal maps of cortical hemodynamics [1-5]. The use of a red-green-blue (RGB) image acquired by a digital RGB camera is promising as a technique of rapid and cost-effective intraoperative imaging.
