The human body is the collective body of large number of cells, which are in continuous growth, development, differentiation, regeneration, and death.  The cells renew themselves by self-division.  There are about 25,000,000 cells dividing in adult human body per second. And the dividing speed of the blood cells is about 100,000,000/s. During the process of dividing and growth, the nucleus and the extranuclear electron, the basic components of the cell with electricity, are making the high- speed movement and changing. In the meanwhile, the electromagnetic waves are radiating outward constantly. The electromagnetic waves stand for the different specific states of human body, such as healthy state, sub-healthy state and disease state. In different states, the corresponding electromagnetic waves are different. Thus, we can check out the human body state if these specific electromagnetic waves are detected. 

In quantum medical area, the fundamental reason for people suffering disease is that the spinning and the orbiting of the electron have changed, which makes the atoms change, which causes the biological micromolecule change. Therefore, the biological macromolecule changes, gradually, the whole cell starts to change, and ultimately the whole organ change. Since the electron is a charged body, when the spinning and the orbiting of it have changed, the electromagnetic waves inside will change accordingly. The energy of electromagnetic wave variation, which is caused by the different states of dieses and nutrition, is very weak, usually only Ns Gaussian or To Micro-Gauss. The frequency and the energy of the magnetic field are measured by holding the sensor with hand. It is similar to the theory of listening to the radio. There are various wireless waves in the air, but if you want to listen to certain broadcasting station, you should modulate the radio to the same frequency, which causes the resonance, and then, the radio can get the specific radio station. Quantum Resonance is based on this theory as well.
