We developed and tested the feasibility of a new dynamic imaging method for kinematic measurement of the knee joint. One subject was scanned using a validated static method, as well as using modified (fast) static and dynamic methods under load and over a range of motion. Differences between the standard and fast static methods were within expected errors. The dynamic method provided more data in a shorter time, and produced similar results to the static scans. The results of this work indicates that this is a viable new method for measuring the kinematic rotations and translations of the knee bones.
