There are eight steps in the marker-based XROMM workflow:

1) Implant radiopaque bone markers

2) Record biplanar x-ray videos of movement

3) Calibrate

4) Analyze x-ray videos to extract XYZ coordinates of radiopaque markers

5) Create 3D polygonal mesh bone and marker surface models

6) Measure XYZ coordinates of marker centroids relative to polygonal mesh bone models

  • Instructions for this step are available if you are working with models from CT scans. Laser scan procedures are different and instructions are not yet available.
  • For CT models, this step is done in Maya using the XROMM Maya Tools

7) Calculate rigid body kinematics from XYZ marker positions

8) Produce XROMM animations in Autodesk Maya
