Abstract

During irradiation with an Ar+-and Kr+-laser the temperature rise in living and dead tissue was measured in various depths. The contribution of the blood flow to the heat transport during irradiation was found to be small. The influence of the different depths of penetration and backscattering at the blue-green Ar+-and the red Kr+-radiation was investigated. The measurements compared with theory show reasonable agreement for an one-dimensional model below 100 degrees C. The results are discussed with respect to laser application in medicine.

摘要

在用氩离子激光和氪离子激光照射期间,测量了活组织和死组织不同深度处的温度升高情况。结果发现,照射期间血流对热传递的贡献很小。研究了蓝绿色氩离子辐射和红色氪离子辐射在不同穿透深度和反向散射方面的影响。与理论进行比较的测量结果表明,对于低于100摄氏度的一维模型,两者具有合理的一致性。针对激光在医学中的应用对结果进行了讨论。
