Abstract

The invention provides a ventilating device for a magnetic resonance imaging system and the magnetic resonance imaging system. The ventilating device comprises a fan and a regulating element. The fan is used for generating airflow flowing through a detected object in the magnetic resonance imaging system, and the regulating element is used for regulating the operating parameter of the fan according to a heat signal used for showing the heat change of the detected object. Due to the ventilating device and the magnetic resonance imaging system including the ventilating device, the user experience of the magnetic resonance imaging system is strengthened, the high absorptivity receiving and long-time checking capacity of the detected object is improved, and medical risks caused by body overheating are lowered.

Description

technical field [0001] The invention relates to a magnetic resonance imaging system, in particular to a ventilation device for a magnetic resonance imaging system. Background technique [0002] Magnetic resonance imaging is a biomagnetic nuclear spin imaging technology that has developed rapidly with the development of computer technology, electronic circuit technology, and superconducting magnet technology. In MRI, human tissue is placed in a static magnetic field B 0 In the process, the radio frequency pulse with the same frequency as the precession frequency of the hydrogen nucleus is used to excite the hydrogen nucleus in the human tissue, causing the hydrogen nucleus to resonate and absorb energy; after the radio frequency pulse is stopped, the hydrogen nucleus emits a radio signal at a specific frequency, and the The absorbed energy is released, collected by the receiver outside the body, and the image is obtained after computer processing. [0003] During the scanni...
