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.

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 bone models

6) Calculate rigid body kinematics from XYZ marker positions

7) Produce XROMM animations in Autodesk Maya

For markerless XROMM, create Maya x-ray cameras and load undistorted video into Maya, then create rotoscoping controls or use the Pan and Scan tool for Rotoscoping.

* 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.
