X-Ray Reconstruction of Moving Morphology (XROMM) is an x-ray imaging and computational process that produces precise and accurate 3D movies of skeletal movement.
See xromm.org for more information.
There are seven steps in the marker-based XROMM workflow:
1) Implant radiopaque bone markers
2) Record biplanar x-ray videos of movement
4) Create 3D polygonal bone surface models
5) Measure XYZ coordinates of markers relative to polygonal 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
* Note: If you want to remove fluoroscope distortion from x-ray movies (i.e. undistort or correct the movies), use X-rayProject version 2 or later. We are no longer updating VideoCorrect or FluoroCorrect MATLAB programs. Undistorting a video is a two-step process: 1. Create an *UNDTFORM file and 2. Click Undistort Video in the X-rayProject window.
