X‐Ray Reconstruction of Moving Morphology (XROMM) comprises a set of 3D X‐ray motion analysis techniques that merge motion data from in vivo X‐ray videos with skeletal morphology data from bone scans into precise and accurate animations of 3D bones moving in 3D space. XROMM methods include: (1) manual alignment (registration) of bone models to video sequences, i.e., Scientific Rotoscoping; (2) computer vision‐based autoregistration of bone models to biplanar X‐ray videos; and (3) marker‐based registration of bone models to biplanar X‐ray videos. Here, we describe a novel set of X‐ray hardware, software, and workflows for marker‐based XROMM. Refurbished C‐arm fluoroscopes retrofitted with high‐speed video cameras offer a relatively inexpensive X‐ray hardware solution for comparative biomechanics research. Precision for our biplanar C‐arm hardware and analysis software, measured as …
