LIGHT SHAPING TECHNIQUE FOR UV PSORIASIS THERAPIES

进行牛皮癣紫外线光疗的皮肤科医生需要一种灵活的工具，该工具可以优化紫外线辐射剂量，并自动保护患者S身体的健康部位免受过量紫外线辐射的影响。为了满足这一需求，物理光学公司(POC)提出了一种通过光纤传输光的紫外光整形技术。通过使用POC S专有的电子可调光整形漫射器和光纤，这项技术将允许医生调整光点的大小和形状，以与给定皮肤病变的形状和大小相对应。它还将提高光线的均匀性和强度，从而避免对屏蔽材料的需要。POC S提出的技术将构成对现有UV光源的廉价连接，并将提高治疗效率并减少副作用。建议的商业应用建议的技术的低成本组件将使其作为家用紫外光治疗装置的附件具有市场前景。它可用于多种医疗照明系统，与内窥镜相结合，以及用于牙科实践。

Dermatologists who perform psoriasis UV phototherapy need a flexible tool that will optimize the UV radiation dose and automatically protect healthy parts of a patient s body from excessive UV radiation. To meet this need, Physical Optics Corporation (POC) proposes a UV light shaping technique with light delivered through fiber optics. By utilizing POC s proprietary electronically tunable light shaping diffuser (ETLSD) and fiber optics, this technique will permit a physician to adjust the size and shape of a light spot to correspond to the shape and size of a given skin lesion. It will also increase light uniformity and intensity, thereby avoiding the necessity for shielding material. POC s proposed techniques will constitute an inexpensive attachment to existing UV light sources, and will increase therapeutic efficiency and reduce side effects. PROPOSED COMMERCIAL APPLICATION The low cost components of the proposed technique will make if marketable as an attachment to home UV phototherapy units. It can be used in numerous medical illumination systems, combined with endoscopes, and in dental practices.
