I've seen a lot of confusion over the terms "bioscan" and "biofeedback," so I thought it useful to include an article on the difference between the two.
Biofeedback involves having body functions -- often brain waves and heart rate -- monitored in such a way that someone can observe the readings and use various techniques (like relaxation, breathing, etc.) to control the body functions. This is useful, for instance, for those with fast heartbeats who need to learn ways of calming them. By seeing the results of breathing, visualization, etc. on their body in a clinical setting, they're better able to control their bodies outside the clinical setting as well. You can see images to the right that represent this kind of therapy.
Bioscans (or "quantum scans"), on the other hand, measure the quantum field of someone's body. There are different methods of doing this. You can click the quantum scan link to read about several of those methods.
