Enhanced optics for a low-cost smart skin imaging system

在加拿大，癌症是导致死亡的主要原因，皮肤癌是这种疾病的常见类型之一。幸运的是，皮肤癌的检测相对容易，因为在大多数情况下，症状可以通过皮肤的视觉检查来识别。然而，接触皮肤科医生的机会有限，常规咨询的等待时间长，是皮肤癌早期诊断的主要制约因素，而早期诊断是成功治疗的关键。为了解决这个问题，MetaOptima开发了MoleScope，这是一种低成本的智能皮肤成像系统。MoleScope有一个光学装置，可以连接到智能手机上，获得高质量的放大图像。使用MoleScope，患者可以监测和跟踪皮肤痣的变化，并通过将可疑皮肤病变的图像发送给他们的皮肤科医生来快速评估癌症风险。本项目旨在改进MoleScope设备现有的光学设置，通过抑制光学像差和杂散反射来提高图像的质量和分辨率。我们还将设计和开发一种新的光学放大镜系统，可以选择放大倍率，包括更高的放大倍率能力。该项目的结果将使MoleScope能够以更高的精度用于检查广泛的医学相关结构。

Cancer is the leading cause of death in Canada, and skin cancer is one of the common types of the disease.Fortunately, the detection of skin cancer is comparatively easy since in most cases the symptoms can berecognized on visual inspection of the skin. However, limited access to dermatologists and long wait times forroutine consultation are the main constraints for early diagnosis of skin cancer, which is key to a successfultreatment. To address this problem, MetaOptima has developed MoleScope, a low-cost, smart skin imagingsystem. The MoleScope has an optical setup that attaches to a smartphone to acquire high-quality magnifiedimages. Using a MoleScope, patients can monitor and track changes in their skin moles and obtain rapidevaluations of cancer risk by sending the images of suspect skin lesions to their dermatologist.The aim of this project is to modify the current successful optical setup of the MoleScope device to improvethe quality and resolution of the images by suppressing optical aberrations and stray reflections. We will alsodesign and develop a new optical magnifier system with a choice of magnification including a highermagnification capability. The result of this project will allow the MoleScope to be used to examine a broaderrange of medically relevant structures with improved accuracy.
