Abstract
We have developed a three-dimensional image reconstruction algorithm to recover the spatial distribution of optical properties in human finger joints for early diagnosis and monitoring of rheumatoid arthritis. An optimization method iteratively employs a light propagation model based on the equation of radiative transfer for recovering the unknown absorption and scattering coefficient distribution for near-infrared light inside the joint tissue. We show threedimensional image reconstruction results of finger joints and compare them to two-dimensional images of previous studies.
