At an expo, there was a chiropractor (I've never been to one) who scanned people's upper neck with a device that measured heat I think. They showed a picture on the computer of the areas that have anomalies. Does anyone know what type of machine this may be?

my chiropractor uses this type of computer analysis. what hers does, vertebrae by vertebrae, is to measure the electrical impulses passing from one side to the other. it shows where there are blockages in the energy field, as well as stress overloads. if you need the name of the actual system, i can call her.
