NMR (Nuclear Magnetic Resonance)-imaging (NMRI=Nuclear Magnetic Resonance Imaging) diagnostic method is without radiation injury, without wound, no pain, nothing danger, without any infringement, be one of imaging examination means of state-of-the-art non-damage on our times to human body.The development of nuclear magnetic resonance imaging system, has embodied current hard-core technology level.The chief component structure of NMR system comprises: magnet system, radio system, gradient system, spectrometer system and computer system, also have shielding harness etc.In this numerous system, also exist many subsystems, that is to say that the composition of nuclear magnetic resonance imaging system is very complicated, scientific and technological content is very high, belongs to high, precision and frontier checkout facility; Its any one system, if there is problem or fault, can directly have influence on the normal operation of this equipment, has influence on the use safety of this equipment; Especially the most important thing wherein---magnet system, key object especially in whole imaging system composition.
Especially, superconduct magnetic resonance machine all has higher requirement to power supply supply, ambient temperature, humidity, dust-proof purifying, cooling system etc., and the quality of these factors, is the key factor that is related to service life of a machine.Superconduction nuclear magnetic resonance imaging system has used this superconductivity theory just: when temperature T is reduced to critical temperature (critical temperature), resistance becomes suddenly 0 (can not measuring).Electric current can be endless flow.The magnetic field of superconduct magnet is set up in superconduction environment as superconducting coil galvanization produces high-intensity magnetic field.In the ideal situation, once magnetic field is set up, as long as maintain the ultra-low temperature surroundings of superconducting coil, high-intensity magnetic field is with regard to long-term existence.Superconductor is mainly the multifibres recombination line of niobium, titanium and copper, and its operating temperature is 4.4K (268.8 ℃).Therefore we must set up superconduction environment, and superconductor is placed under operating temperature 4.2K.The ultra-low temperature surroundings that the superconducting coil of magnetic resonance is normally worked to obtain it by the method being immersed in low-temperature liquid helium, although magnet has adopted vacuum insulation structure, but due to many factors such as support structure, can not stop conduction of heat completely, so liquid helium can be taken the heat of importing out of with the form of evaporation, to maintain the temperature of 4.2K.Helium is rare noble gas, and critical temperature is minimum, the gas of difficult liquefaction, and China's content is extremely low, and basic dependence on import completely, so expensive.For reducing the evaporation of liquid helium, magnetic resonance has been equipped with refrigeration system, provides cooling to reduce liquid helium evaporation.Water chiller, liquid helium compressor and the cold head of NMR system just look like that human heart is the same, need whole day twenty four hours ceaselessly to move a moment.
At present; there is system status monitoring system in international each large medical NMR system manufacturer; but these systems have obvious limitation: 1, monitoring range is little; mainly for the kernel subsystems monitoring of magnetic resonance; but ignored the subsystem such as water cooling unit, air-conditioning, and the fault of these auxiliary devices all can cause whole magnetic resonance to shut down.2, range of application is little, the monitoring system of manufacturer need to be connected to headquarters server by internet, can threaten to magnetic resonance machine and Information Security thereof, therefore some important medical institutions (such as Army Hospital) all forbid to install this type of monitoring system.3, response speed is slow, less economical, the monitoring system of manufacturer reaches external server fault, and then sends to the technical staff of producer by mail, and technical staff is by the hospital architecture project teacher that tells by telephone, this process need regular hour, not prompt enough and only towards paying customer.4, very flexible, at present the monitoring system of manufacturer is to be all bundled in above system host, cannot remote monitoring, cannot transplant other equipment that is generalized to.
