DMX stands for Digital Motion X-ray and was first utilized in 1994. Digital motion X-rays are taken in a standing, weight-bearing position and it analyzes the bone juxtaposition throughout the joint in motion. It takes around 30 images per second at low radiation. DMX can detect ligament injuries in mid-range, as well as small fractures. This picture-in-picture technology allows for visualization of patient reactions through movement. It also allows for the visualization of internal structures at the moment of pain.
