Abstract

Interest in lasa ablation of deep seated anthymic foci in myocardium has created the study for the optical properties of myocardiu~l] . With the usc of a Ti:Sapphire laser and intergrating sphere me&ods[2] we have investigated the spectral range of 690-10SOnm of myocardial tissue. Collimated 8s wet1 as diffuse light was transmitted hough bloodless tissue and measurements of the transmission and reflection were made. From these measuremeats the absorption, scattering and r e d u d scattering coefiiecients were determined. A minimum of these pprameters were found to be in the range of 800-84onm.

局部激光消融室性心动过速心肌组织光学窗口的探讨
对激光消融心肌深部病灶的研究开创了对心肌光学特性的研究[1]。我们利用钛蓝宝石激光器和积分球方法[2]研究了心肌组织690-10SOnm的光谱范围。在无血组织中散射光,并测量其透射和反射。根据这些测量结果,确定了吸收系数、散射系数和散射系数。这些参数的最小值在800-84onm的范围内。
