title: A digitizer with exceptional accuracy for use in prosthetics research: a technical note.
abstract: A mechanical digitizer was developed for use in prosthetics research where measurements of small differences in shape are of interest. Root-mean-square error was 0.075 mm in the radial direction, 0.05 degrees in the tangential direction, and 0.1 mm in the vertical direction. The system has potential use for time-dependent assessment of changes in socket and residuum cast shape, assessment of socket fabrication systems, and development of accurate prosthetic finite element models.
