Does the country prohibit the detection of radiation by quantum resonance in the medical field?

If you really want to get to the bottom of it: nuclear magnetic resonance is still dangerous to the human body. First of all, the principle: nuclear magnetic resonance (MRI) is a bio-magnetic spin imaging technology, which uses the characteristics of nuclear spin motion to generate signals in an external magnetic field after being excited by radio frequency pulses, which are detected by a detector and input into a computer, and then displayed on the screen after being processed and converted. In other words, nuclear magnetic resonance is different from CT, X-ray and radiological images. It is not radioactive. It only relies on a magnetic field with a certain intensity to excite the atomic spin axes inside the object to keep consistent, thus generating a spin pulse, and then generating the required image through this pulse signal. But if we have to study the harm it brings to human body, the main reason is that strong magnetic field will cause metal displacement, such as metal fragments in eyes and brain, which will lead to brain injury and blindness under the action of magnetic field. Therefore, people with a history of brain surgery and eye injury, as well as welders, must pay attention to taking X-rays of their heads in advance. In addition, the strong magnetic field will make metal objects such as forks, keys and oxygen cylinders fly to the equipment center, thus causing casualties of patients. So it is forbidden to have any metal objects in the house. As for similar radiation damage, the role of nuclear magnetic resonance is not obvious. As long as you don't shoot every day and every year, there will be no side effects and you don't need to wear strict protective equipment. Don't be too nervous, as long as you pay attention to the above problems, MRI will not bring any side effects. Imagine the safest sponge, and improper use will also have security risks.
