“…Pulsed Photothermal Radiometry (PPTR) technique based on the analysis of thermal emission kinetics from tissue subjected by pulsed laser heating is the effective method to investigate laser radiationtissue interaction and to design laser medicine systems with feedback. [1][2][3][4] The thermal emission S (t) registered by PPTR technique is determined by the tissue temperature rise T (x,t) caused by laser irradiation. The temperature rise itself is governed by laser operating conditions as well as optical and thermophysical properties of tissue and boundary conditions of heat transfer (tissue-air).…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
