We developed a clinical probe capable of acquiring simultaneous short wavelength infrared (SWIR) reflectance and occlusal transillumination images of lesions on tooth proximal and occlusal surfaces to reduce the potential of false positives. The dual probe is 3D-printed and the imaging system uses a Ge-enhanced camera and fiber-optic light sources that use SWIR light at 1300-nm for occlusal transillumination and SWIR 1450-nm light for reflectance measurements. The purpose of this study was to test the performance of the probe on extracted teeth prior to commencing clinical studies. The dual probe was used to image extracted teeth with proximal and occlusal lesions. SWIR images of each tooth were compared with micro-CT images to assess performance.
我们开发了一种临床探针，能够同时获取牙齿近中面和咬合面病变的短波红外（SWIR）反射率和咬合面透照图像，以降低假阳性的可能性。该双探针采用3D打印，成像系统使用增强型锗相机和光纤光源，其中1300纳米的SWIR光用于咬合面透照，1450纳米的SWIR光用于反射率测量。本研究的目的是在开始临床研究之前，测试该探针在拔除牙齿上的性能。使用双探针为有近中面和咬合面病变的拔除牙齿成像。将每颗牙齿的SWIR图像与微型计算机断层扫描（micro-CT）图像进行比较，以评估性能。
