Why video x-ray?

1X-rays require a certain degree of radiation exposure to make a 'picture'.  Sometimes it is important to balance the damage of the radiation exposure versus the valuable information that an x-ray provides.  With video we use very small amounts of radiation.  Instead of catching the x-ray beam that goes through the patient's body on x-ray film,  the beam enters an image intensifying tube which reduces the amount of radiation needed to make an image.  Video also gives us a real-time view of the spine and allows us to see motion and identify potential subluxations.  With such low amounts of radiation we are able to re-x-ray to see how the spine changes as subluxations are reduced and corrected.   Dr. Hunt has been studying motion x-rays like this since 1991.
