Description

Technical Field

[0001] The utility model relates to the field of nuclear magnetic resonance medical equipment, in particular to a power generation device for a vehicle-mounted nuclear magnetic resonance system and a vehicle-mounted nuclear magnetic resonance system. Background Art

[0002] For existing vehicle-mounted MRI systems, permanent magnet systems with easy maintenance are generally used. For vehicle-mounted MRI systems equipped with superconducting MRI systems, in order to avoid the loss of current to establish the magnetic field, the coil of the magnet needs to remain in a superconducting state. Once the magnetic field is established, as long as the temperature of the magnet is maintained in an ultra-low temperature environment, a stable strong magnetic field will always exist. In order to ensure the ultra-low temperature environment of the magnet, superconducting MRI uses liquid helium for cooling. At the same time, a water chiller and a cold head are used to re-liquefy the volatilized liquid helium to form a sustainable cycle.

[0003] Due to the particularity of superconducting magnetic resonance, it has high requirements for power supply continuity. Existing on-board nuclear magnetic resonance systems are usually powered by mains electricity. Once the power supply is interrupted, the water cooler and the cold head will not work, which will directly cause the volatilized liquid helium to be unable to be re-liquefied, breaking the balance of the cycle. Liquid helium is a precious non-renewable resource, and volatilized liquid helium will cause huge economic losses. As the liquid helium continues to evaporate, the liquid helium level in the magnet will continue to decrease. After it drops to a certain level, even if the power supply is restored, the magnetic resonance cannot be scanned normally. When the liquid helium level is lower than the critical line, the remaining liquid helium can no longer maintain the superconducting state of the magnet coil. The heat generated by the coil current will directly cause the magnet to lose its superconductivity, and the remaining liquid helium will evaporate quickly. After the liquid helium evaporates, the magnet coil will continue to heat up to room temperature. If you want to use magnetic resonance later, you need to add liquid helium again to cool the magnet coil back to the superconducting state and re-excite it. This will also cause huge economic losses.

[0004] In addition, the air conditioner will stop working after the power is cut off, and the temperature and humidity in the car will gradually get out of control. This will not only increase the risk of equipment damage, but also increase the probability of quenching of the magnetic resonance equipment. Utility Model Content
