我们开发了一种临床探头，能够同时采集短波长红外（SWIR）反射和咬合透照图像的病变牙齿近端和咬合面，以减少假阳性的可能性。双探头是3D打印的，成像系统使用Ge增强型相机和光纤光源，使用1300 nm的SWIR光进行咬合透照，使用SWIR 1450 nm光进行反射测量。本研究的目的是在开始临床研究之前测试探针在拔牙上的性能。双探头被用来成像提取牙齿与近端和咬合病变。将每颗牙齿的SWIR图像与micro-CT图像进行比较，以评估性能。
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.
