Digital Motion X-Ray (DMX) is simply a new type of fluoro-based x-ray system, coupled with new digital and optic technology, allowing clinicians to view the spine in real-time motion at 30 x-rays per second. The procedure is performed with the patient standing and actively moving in a weight-bearing position within the system.

DMX is a digital movie of x-ray in motion and it can be:

• Printed and emailed as still x-rays
• Stored on a hard drive
• Recorded on:
  • DVD
  • CD-ROM
  • Mini-DV tape
  • Super VHS tape

Traditionally, diagnosis of whiplash injuries rely upon non-moving diagnostic procedures, such as static x-rays, stress view x-rays, CT, and MRI. During these tests, patients are asked to stand or lie still: "Don't move " and/or "Hold your breath." Patients hurt more when they move, and pain is commonly an indicator of injury. The majority of these non-moving diagnostic tests come out negative or unremarkable.
