我们已经开发出一种临床探头，能够同时获取短波长红外（SWIR）交叉偏振反射和咬合透照图像的病变牙齿近端和咬合面。我们假设双SWIR反射和透射探头将通过减少假阳性来提高设备的诊断准确性，因为在反射和透射图像中不太可能存在混淆的结构特征或镜面反射。此外，双探头将提供有关病变严重程度的补充诊断信息，以帮助区分牙齿表面的早期浅表病变和深度穿透性病变。双探头是3D打印的，并配备了紧凑的InGaAs相机和宽带超发光二极管光源，该光源发射1300 nm的宽带光用于咬合透照，发射1600 nm的光用于交叉偏振反射测量。使用这种新型探头采集的第一个临床图像。
We have developed a clinical probe capable of acquiring simultaneous short wavelength infrared (SWIR) cross-polarized reflectance and occlusal transillumination images of lesions on tooth proximal and occlusal surfaces. We hypothesize that the dual SWIR reflectance and transillumination probe will improve the diagnostic accuracy of the device by reducing false positives since it is unlikely that confounding structural features or specular reflection are going to be present in both reflectance and transillumination images. In addition, the dual probe will provide complementary diagnostic information about lesion severity to help discriminate early superficial lesions on tooth surfaces from deeply penetrating lesions. The dual probe was 3D printed and equipped with a compact InGaAs camera and broadband superluminescent diode light sources that emit broadband light at 1300 nm for occlusal transillumination and 1600 nm light for cross-polarization reflectance measurements. The first clinical images acquired using this novel probe are presented.
