Journal ArticleDOI
Measurement and calculation of the two-dimensional backscattering Mueller matrix of a turbid medium.
Brent D. Cameron,M. J. Raković,Mehrube Mehrubeoglu,George W. Kattawar,Sohi Rastegar,Lihong V. Wang,Gerard L. Coté +6 more
TL;DR: Both experimental and Monte Carlo-based simulation results for the diffusely backscattered intensity patterns that arise from illumination of a turbid medium with a polarized laser beam are presented.
Journal ArticleDOI
Laser thermal ablation
TL;DR: Continuous wave and pulsed laser ablation of tissue is described as an explosive event and a decrease in water content dramatically alters the local rate of heat generation of laser radiation above 1.3 μm since water is the primary absorber.
Journal ArticleDOI
Light backscattering polarization patterns from turbid media: theory and experiment.
M. J. Raković,George W. Kattawar,Mehrube Mehrubeoglu,Brent D. Cameron,Lihong V. Wang,Sohi Rastegar,Gerard L. Coté +6 more
TL;DR: A new numerical method that allows simultaneous calculation of all 16 elements of the two-dimensional Mueller matrix is used and compared calculations to measurements from a turbid medium that consisted of polystyrene spheres of different sizes and concentrations in deionized water.
Proceedings ArticleDOI
Theoretical analysis of equivalency of high-power diode laser (810 nm) and Nd:YAG laser (1064 nm) for coagulation of tissue: predictions for prostate coagulation
TL;DR: In this paper, a profile of light, temperature and thermal damage distributions in tissue based on measured optical properties is examined theoretically for high power diode laser (810 nm) and Nd:YAG laser (1064 nm).
Journal ArticleDOI
Nonlinear finite-element analysis of the role of dynamic changes in blood perfusion and optical properties in laser coagulation of tissue
TL;DR: In this paper, a nonlinear finite-element program was developed to simulate the dynamic evolution of coagulation in tissue considering temperature and damage dependence of both the optical properties and blood perfusion rate.
