Biomedical application of various techniques for visualization of laser effect on transparent biomaterials

Visualization study of hydrodynamic flow and thermoelastic stress-fields resulted in laser effect on transparent biomaterials and tissues are presented. Various shlieren- and shadowgraph schemes for visualization of thermomechanics effect of laser pulses on the visco-elastic biomaterials and biotissues were considered. Noncontact techniques for control of the general thermodynamic parameters of materials in zone of laser-tissue interaction have been designed. Photothermal and hydraulic effects on biological media irradiated by repetitive pulse laser radiation have been studied using spatial and time-resolved dynamics of the images video recorded. Biofunctional nanoparticles masstransfer in laser-stimulated diffusion in the transparent biomaterial are studied. Bioimaging and image processing problems are considered for vision control system designed to laser medicine.
