The study of the light fluence rate distribution in blood

It is necessary to understand the light fluernce rate distribution in blood in the field of laser medicine.Port wine stain is one of the most common dermal diseases,and the means of laser treatment was often used.Assume that blood is distributed homogeneously over the dermal volume,instead of being enclosed in discrete vessels,and laser treatment of port wine stains has often been modelled.The paper calculates and analyses the result under the assumption.
