| 摘 要： | 提出了近红外光纤探头"视距"模型.通过Monte Carlo模拟和两种不同光学性质的双层模型实验,得到了100 μm探头"视距"的经验公式.提出了三层模型的"视距"定义,给出了"层分辨率"的概念,并通过大鼠大脑的试验得到验证.利用近红外光纤探头"视距",可以区分不同的脑组织,在深脑探测手术中进行导航.探头"视距"提出了一个近红外探头视距研究的普遍方法,对光纤探头的设计有重要意义.

| Abstract: | The near infrared technique is used for 3D accurate location of the probe in neuro-surgery of Parkinson's disease. The optical probe's Look Ahead Distance(LAD) can be used to guide the probe. By the simulation of Monte Carlo and research of the 2－layer laboratory phantoms,the LAD's formulations are given. With the comparison of LADs from both Monte Carlo and fitting equation,it can be proved that the formulations are correctly . Using LAD can improve the precision of the location and shorten the time of operation. Analyse the 3－layer model and give the definition of Layer Resolution(LR). At last,use the LR to locate the optical probe in the animal test. |
