X-ray System to Show Moving Bones in 3-D

A new project, being developed at Brown University, promises to improve our understanding of the complex motions of bones and joints.

Computed tomography, or CT, delivers detailed 3-D images, but CT scanners are too slow to capture rapid motion. Cinefluoroscopy, a technique that uses X-rays to view objects, can produce moving images in two dimensions, but not 3-D.

The new system, dubbed CTX, will combine the 3-D capability of CT scanners and the real-time movement tracking of cinefluoroscopy. CTX technology is expected to deliver images with exceptional precision and detail. Researchers will be able to track 3-D skeletal movements with 0.1 millimeter accuracy and see the equivalent of 1,000 CT images per second.
