Abstract
The article analyzes a traditional idea on the description of Low Level Laser Irradiation (LLLI) resulting from some isolation (gap) of clinic-biological and optic studies in the sphere of Low Level Laser Medicine. The author uses a conventional parameter `Specific Power Density,' Ps (mW/cm3) connected with both power characteristics of laser and optical properties of irradiated biological subject. The attenuation of the LLLI in biotissue is described with a gradient P(x), where x is a distance to the source. If the distributed intensity of LLLI is integrated over the volume V so one can obtain integral intensity SP(mW). Let us divide integral intensity by the volume: SP/V. This very ratio is Specific Power Density P (mW/cm3). The calculation of energetic LLLI parameters of whole blood intravenously is submitted as an example of use of the Specific Power Density.
