[Photochemical reactions in bone tissue induced by excimer laser ultraviolet].
A phenomenological model of an increase in ultraviolet absorption in bone tissue induced by ultraviolet radiation of excimer laser has been developed. It is assumed that the increase in absorption is related to photochemical reactions in collagen. The model accounts for changes in the intensity of laser radiation due to its absorption inside the specimen. From the comparison of experimental and calculated results the parameters of the photochemical model were estimated. The temperature fields in the specimen were calculated with regard to laser-induced changes in absorption coefficient. The limits of applicability of the model are discussed.
