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

1) Implant radiopaque bone markers

2) Record biplanar x-ray videos of movement

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

4) Create 3D polygonal bone surface models

5) Measure XYZ coordinates of markers 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

6) Calculate rigid body kinematics from XYZ marker positions

7) Produce XROMM animations in Autodesk Maya
