CRITICAL UPDATE: Use new XMALab software for marker-based XROMM, and also for undistorting and calibrating biplanar X-ray setups.

XMALab replaces MATLAB XrayProject. See Bitbucket XMALab wiki for XMALab User Manual (not this wiki). 

Note: there is a Table of Contents we recommend you use to navigate this xrommwiki. The links on this page are obsolete.

There are five 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) Produce XROMM animations in Autodesk Maya

* FluoroCorrect:  A Matlab package for undistorting videofluoroscopy sequences is available on SourceForge Documentation on the usage and development of this software package can be found here:  Video Correction Documentation    Some FluoroCorrect instructions are available.

At Brown University we have developed three main approaches to XROMM:

1) Marker-based XROMM workflow (Brainerd et al., 2010)
2) Scientific Rotoscoping workflowi.e. manual markerless XROMM (Gatesy et al., 2010)
3) XROMM AutoScoper software, i.e. automated markerless XROMM (Miranda et al., 2011)
New: XROMM Undistorter, stand-alone undistortion program

We have also developed the X-ray Motion Analysis Portal (XMA Portal) for storing, viewing and managing X-ray movie data and associated metadata.
