Abstract
|
|
|
This paper proposes a method of noninvasive reflectance light to measure the blood fractional volume(Vb) and oxygen saturation(SO2) of biological tissue. We chose the red light of 660nm and infrared light of 880nm. In Vivo reflectance data were
obtained
the physiological changes from the surface of the skin over the calf in human subject. The reflected light intensity from different layers within a biological tissue was measured by specially designed reflectometer to apply photon path diffusion
model.
The collected data represent the changes of blood fractional volume and oxygen saturation at each reflected light wavelengths. This study uses the experimental methods to assess the physiological changes due to heat. The result presented in this
paper
demonstrate to measure consistent changes in tissue optical properties during heat.
