Journal ArticleDOI
Optical and acoustic properties at 1064 nm of polyvinyl chloride-plastisol for use as a tissue phantom in biomedical optoacoustics.
Gloria Spirou,Alexander A. Oraevsky,I. Alex Vitkin,I. Alex Vitkin,William M. Whelan,William M. Whelan +5 more
TL;DR: The speed of sound and density of PVCP are similar to tissue, and together with the user-adjustable optical properties, make this material well suited for developing tissue-equivalent phantoms for biomedical optoacoustics.
Journal ArticleDOI
A Novel Strategy For Monitoring Laser Thermal Therapy Based on Changes in Optothermal Properties of Heated Tissues
TL;DR: In this paper, a method to monitor the progress of laser thermal therapy by detecting temperature-induced changes in optical propagation has been developed, where point optical intensity measurements are indicative of a larger sampling volume of optothermal events.
Journal ArticleDOI
Investigations of large vessel cooling during interstitial laser heating.
TL;DR: A three-dimensional, time-dependent finite difference model of interstitial laser heating around large vessels is presented and indicates that significant reductions in the extent of a thermal coagulation boundary can occur if a large vessel is situated inside the normal coagulated zone.
Journal ArticleDOI
Interstitial laser photocoagulation: Nd:YAG 1064 nm optical fiber source compared to point heat source.
TL;DR: This preliminary study suggests that a point heat source produces a larger volume of thermal coagulation than a point optical source delivering the same power.
Journal ArticleDOI
Study of laser-induced thermoelastic deformation of native and coagulated ex-vivo bovine liver tissues for estimating their optical and thermomechanical properties
TL;DR: The results demonstrate that differences in the tissue expansion dynamics arise from higher values of elastic modulus for coagulated liver samples compared to native ones.
