病理晶体鉴定在风湿病学中常规用于诊断关节炎疾病如痛风,并且依赖于偏振光显微镜作为医疗专业人员使用的金标准方法。在这里,我们提出了一个单镜头计算偏振光显微镜的方法,重建的透射率,延迟和慢轴方向的双折射样品使用一个单一的图像与像素偏振相机捕获。这种方法快速,操作简单,与所有现有的标准显微镜兼容,无需大量或昂贵的修改。我们通过对滑液中发现的三种不同类型的晶体进行成像,并使用单个图像重建这些样品的双折射信息,而不受样品视场内单个晶体取向的影响,证明了我们方法的成功。我们相信这项技术将以低成本提供更高的灵敏度、特异性和速度,用于临床诊断滑液和其他体液中发现的晶体。
Pathological crystal identification is routinely practiced in rheumatology for diagnosing arthritis disease such as gout, and relies on polarized light microscopy as the gold standard method used by medical professionals. Here, we present a single-shot computational polarized light microscopy method that reconstructs the transmittance, retardance and slow-axis orientation of a birefringent sample using a single image captured with a pixelated-polarizer camera. This method is fast, simple-to-operate and compatible with all the existing standard microscopes without extensive or costly modifications. We demonstrated the success of our method by imaging three different types of crystals found in synovial fluid and reconstructed the birefringence information of these samples using a single image, without being affected by the orientation of individual crystals within the sample field-of-view. We believe this technique will provide improved sensitivity, specificity and speed, all at low cost, for clinical diagnosis of crystals found in synovial fluid and other bodily fluids.
