A team of researchers at Texas A&M University became the first to use dynamic X-ray technology to successfully map the lumbar spine. The project, led by Dr. Xudong Zhang, seeks to investigate lower spine-related disorders. The computerized visuals produced in the study will provide a stepping stone for further research on the treatment of lower back pain and other spinal injuries.
In contrast to the static X-ray images that allow doctors to diagnose broken bones, Zhang’s team used multiple X-ray sources and high-speed cameras to track and record bones in motion. The recorded sequences were then converted into pinpoint-accurate, fully interactable 3D models.
Zhang explained that these models can be used to conduct research previously impossible with human subjects. “We can only ask our human subjects to perform safe tasks. We can’t ask them to push limits,” he said. “But once we build the subject-specific computer models, we can virtually push their limits and create simulated injury scenarios.”
Conclusions drawn from such research could create promising new treatment options for spinal injuries and disorders, such as exoskeleton devices and new surgical approaches.
