我们提出了第一次完整的三维（3D）体积重建的吸收图像在体外和体内的骨骼和关节从近红外断层扫描测量。使用克莱姆森多通道漫射光学成像仪对嵌入圆柱形散射介质中的人手指和鸡骨进行成像实验。用我们的三维有限元重建算法恢复体积光学图像。我们的研究结果表明，3D成像方法可以提供关节结构/组成的细节，这是不可能从二维成像方法。
We present for the first time full three-dimensional (3D) volumetric reconstruction of absorption images of in vitro and in vivo bones and joints from near-infrared tomographic measurements. Imaging experiments were conducted on human finger and chicken bones embedded in cylindrical scattering media using a Clemson multichannel diffuse optical imager. The volumetric optical images were recovered with our 3D finite element based reconstruction algorithm. Our results show that 3D imaging methods can provide details of the joint structure/composition that would be impossible from two-dimensional imaging methods.
