Abstract
Modelling the diffusion optical characteristics of blood is quite useful in the study of oximetry. The diffusion dipole ofFretterd andLongini (1973) is applied to the solution of the diffusion equation for photons in a blood and saline mixture and an exact solution is obtained. Comparisons are made among this solution and other commonly used techniques. Preliminary measurements on a blood and saline mixture are shown in comparison to the model solutions. The advantages of using the diffusion dipole approach are elaborated.
