Application of digital tomosynthesis to hand radiography for arthritis assessment
Joint space width (JSW) is an important arthritis outcome measure, However, a single radiographic image is a 2D projection of a 3D structure and diseased areas can be obscured. To quantify the JSW in three dimensions, a tomosynthesis algorithm was modified to provide reconstructed slices through the bones that formed joints of the hand. The algorithm produced tomographic slices through the ones of the joint with minimal loss of spatial resolution. It was also discovered that hand radiography is ideally suited for tomosynthesis imaging due to the small amount of scatter and lack of truncation artifacts.
