Paper Abstract

Rheumatoid arthritis of the hand can be characterized and assessed by the narrowing of the phalangeal joint spaces. These are ordinarily scored semi-quantitatively by a radiologist using radiographs of the hand. Software which delineates and measures the joint spaces would be a useful tool for diagnosis. The first part of such an algorithm has been developed which segments and identifies eight individual bones on digitized hand radiographs: the middle and proximal phalanges of the 2nd to 5th digits. The software also determines the locations of the distal interphalangeal, proximal interphalangeal, and metacarpophalangeal joint spaces for each digit.
