Novel illumination system for a smartphone-attachable dermoscope

今天，皮肤科医生不能及时有效地看到足够多的疑似皮肤癌患者 皮肤癌的筛查和早期诊断，皮肤癌是北美最常见的癌症。因此， 患者等待皮肤科医生诊断皮肤癌的时间太长了。MetaOptima设计并开发了 开发了MoleScope(TM)，这是一种低成本的照明放大镜(称为皮肤镜)，可以连接到 智能手机的摄像头可以获取皮肤损伤的放大图像。MetaOptima在World上推出MoleScope 2015年6月在温哥华举行的皮肤科大会。该产品在加拿大、欧盟、美国和 澳大利亚被评为用于捕捉、存储和传输皮肤表面照片的一级医疗设备。 使用MoleScope，患者可以捕获图像，供皮肤科医生远程检查，从而使他们的医生 进行快速有效的皮肤癌诊断。MoleScope智能手机应用程序目前正被用于 随着时间的推移监测皮肤损伤，以便及早识别皮肤癌。 该项目的目的是在MoleScope设备中加入一种新的照明方法。通过 取代了目前专业皮肤镜中使用的精密光学和照明部件，这一新的 照明设计将使MoleScope能够以相当低的成本获得高质量的图像。该项目 还将探索加入偏振滤光片以减少来自皮肤表面的反射的可能性， 使皮肤镜能够在不接触皮肤的情况下快速查看病变，并显示循环 皮肤表面以下的结构对基底细胞癌的诊断非常重要。 与MetaOptima Inc.合作，这项提案旨在吸引和利用PI在光子学和 光学，开发了这种新型低成本皮肤镜的原型。

Today, dermatologists cannot see enough suspected skin cancer patients fast enough for timely and effective screening and early diagnosis of skin cancers, the most common cancer in North America. Consequently, patients are waiting too long to access dermatologists for skin cancer diagnosis. MetaOptima has designed and developed MoleScope(TM), a low-cost illuminated magnifier (called a dermoscope) that attaches to a smartphone's camera to acquire magnified images of skin lesions. MetaOptima launched MoleScope at World Congress of Dermatology in Vancouver in June 2015. The product is registered in Canada, EU, US and Australia as a Class 1 medical device for the capture, storage and transfer of photographs of skin surfaces. Using MoleScope, patients can capture images for remote review by their dermatologist, allowing their doctor to perform fast and effective skin cancer diagnosis. The MoleScope smartphone app is currently being used to monitor skin lesions over time, for early identification of skin cancer. The aim of this project is to incorporate a new method of illumination into the MoleScope device. By replacing the precise optical and lighting components currently used in professional dermoscopes, this new lighting design will enable MoleScope to acquire high quality images at considerably lower cost. The project will also explore the possibility of incorporating polarizing filters to reduce reflections from the skin surface, enabling the dermoscope be used to quickly view lesions without skin contact, and also to reveal circulatory structures below the surface of the skin which are very important for diagnosis of basal cell carcinoma. Working with MetaOptima Inc., this proposal aims to engage and access the PI's expertise in photonics and optics, to develop a prototype of this novel low-cost dermoscope.
