鲜红斑痣光谱测定系统与临床实验

对进行激光治疗的鲜红斑痣患者的皮肤进行光谱定量分析，有利于正确分析患者病变皮肤的光学特性、调整手术设备的工作参数和提高激光治疗的效果。基于对鲜红斑痣形成机理分析及激光临床治疗过程观察，文章建立了一套自动数据采集和分析的光谱系统，可以用于测定鲜红斑痣皮肤微区在380～780 nm范围内的光谱，光谱分辨率为1 nm。实验可测定不同年龄、不同色素痣的光谱曲线，分析并讨论了影响系统工作的原因和解决方法。

Spectral Measurement System and Laser Therapy Experiments for Port Wine Stains

To measure and analyze the spectrum of a small skin region for laser therapy of port wine stain is very useful for clinical doctor to understand the optical characters of patient's pigmented skin,to adjust the output parameters of lasers and then to improve the therapy effects.Based on the analysis of the forming mechanism of port wine stains and clinical operation of the disease,the present paper presents an automatic spectral measurement and analysis system for port wine stain therapy.It can accomplish the spectral detection in the range from 380 to 780 nm,with a spectral resolution of 1 nm.Experiments were performed for patients with various age and pigment diseases;finally,some influencing factors and relevant solutions are enumerated and discussed.
