XROMM
back to protocols | ||
X-ray Reconstruction of Moving Morphology (XROMM) is a 3D imaging technology, developed at Brown University, for visualizing rapid skeletal movement in vivo. [1, 2]
General Procedure
- Collect motion data
- Track markers
- Calculate rigid body transformations
- CT scanning
- Preparing rigid body meshes
- Animate rigid bodies
- Analyze motion data
Collect motion data
- Bi-planar fluoroscopy facilities
- Surgically implant markers
- Calibrate cameras
- Record motion
- Save motion
Track markers
In XMALab.
- Undistort
- Calibrate
- Track

CT scanning
Partner CT scanning facilities.
Preparing rigid body meshes
In Horos.
- Import files
- Import image files to Horos
- Import dicom files
- Remove volume
- Remove volume in 2D viewer
