Abstract
According to expert othopaedic surgeons there is need for medical phantom devices with dimensional metrology traceable to national standards metrology organizations in order to confirm basic Computer Assisted Orthopaedic Surgery (CAOS) systems performance. Phantoms are required for standard and outlier patients that are clinically relevant, lightweight and simple to use. In collaboration with medical professionals a group of NIST researchers has developed a family of novel CAOS phantom devices. The first prototype of these devices will try to address some of the hip arthroplasty metrology testing problems. This prototype has been fabricated and calibrated at NIST and is now being tested by a group of medical researchers.
