LASER-INDUCED PHOTOEMISSIVE IDENTIFICATION OF CALCULI

一种新的基于光学的尿路结石诊断方法 是这样描述的。这一概念是基于有充分根据和 激光诱导荧光(LIF)敏感技术。这一阶段 我的项目将在体外确定，使用几种常见的 LIF是否可以用来识别石头的成分 斯通。观测到的光电子能谱将被记录下来 几种类型的石头。特征光谱特征将 为每一种类型寻找。如果这些石头确实显示出特征 然后，人们可以通过这些光谱来识别未知样本 签名。这可能会导致一种治疗结石的新临床设备 分类，也许更重要的是，最低限度的 基于光纤的侵入性设备，用于现场识别 去接受治疗。

A novel optically based diagnostic for urinary stone identification is described. The concept is based upon the well founded and sensitive technique of laser induced fluorescence (LIF). The Phase I project will determine in vitro, using several commonly found stones, whether LIF can be used to identify the composition of the stone. The photoemission spectrum observed will be recorded for several types of stones. Characteristic spectral signatures will be sought for each type. If the stones indeed shown characteristic features then one can identify unknown samples by these spectral signatures. This could lead to a new clinical device for stone classification, and, perhaps more more importantly, a minimally invasive, fiberoptic based device for in-situ identification prior to treatment.
