Paper Abstract

In this study, we present a simplified spherical approximated-radiative transport model-based reconstruction algorithm for three-dimensional diffuse optical tomography of finger joints. The reconstruction algorithm is tested and validated using a series of phantom experiments and in vivo data from healthy and osteoarthritic joints. In all the phantom and in vivo experiments, the absorption and scattering images are recovered using both the transport model and diffusion approximation based reconstruction algorithms. We observe that while both the diffusion and transport based algorithms can effectively image the finger joints, the transport model based can provide quantitatively improved reconstruction quality over the diffusion approximated based.
