To make the nuclear magnetic resonance equipment work normally, it must meet the condition of resonance, and requires a uniform static magnetic field and an alternating electromagnetic field, so the magnetic resonance equipment is installed in a fully shielded shielding room to prevent other magnetic fields and electromagnetic fields from affecting it.
In addition, because the signal of magnetic resonance to human body scanning is very weak, the electromagnetic field close to the human body can easily interfere with the normal scanning work of magnetic resonance. Therefore, the audio alternating magnetic field signal of the conversation cannot be heard directly by the scanned person, even if it is shielded, there are problems: one cannot be completely shielded; the other is that the shielding layer is metal, which will generate eddy currents that interfere with the magnetic resonance scanning signal.
Since the scan takes a certain amount of time, and the doctor needs to cooperate with the scanned person to do several actions, the scanned person needs to communicate with the doctor in time during the scanning process. But the traditional magnetic resonance equipment does not have a good equipment for the timely communication between the scanned person and the doctor.
In order to solve the above-mentioned problems existing both at home and abroad, Kangdao has developed a passive and non-magnetic dual-way communication device by using the patented technologies of many countries in the world that it has won. The room or not close to the human body can well solve the above problems and improve the detection accuracy.
