Photoheating in a venous blood vessel under near-infrared laser irradiation by a scanning laser beam,which is synchronized with the blood flow velocity,is analyzed numerically by considering the light scattering,absorption,and heat transfer in the blood and surrounding *** scanning regime of the laser irradiation with a wavelength of 1064 nm is found to increase strongly the photoheating of the blood while minimizing the overheating of the skin and the tissues surrounding the blood *** show that the photoheating effect can be additionally enhanced by light-absorbing nanoparticles in the *** proposed approach of dynamic laser photohyperthermia with the scanning laser beam is discussed for potential applications in laser phototherapy.
