摘要

Abstract: Laser ablation and associated bubble formation are known to damage biologic tissue. Imaging of tissue straining during ablation would help to understand and control laser-induced damages. We have used polariscopic imaging to monitor the strain induced by pulsed holmium laser irradiation. A photoelastic tissue phantom, poly(acrylamide) gel, whose viscoelastic properties could be controlled was used to mimic various tissues. The laser energy was delivered to the sample via an optical fiber placed either perpendicularly 1.7 mm from the surface or within the sample. Only compressive strain is observed when the bubble is formed within the phantom, whereas significant tensile strain is induced when the bubble is formed at or next to the surface. !10
