Problems solved by technology
[0003] The magnetic resonance imaging equipment is extremely complicated. The transmitting coil is used as the transmitting antenna. When the magnetic resonance imaging equipment scans, the voltage between the various electronic components in the transmitting coil is relatively high. At the same time, with the appearance of Mars, if the discharge continues, sparks may appear, and these phenomena appear in a closed space, we cannot observe them with the naked eye
[0004] In related technologies, it is judged whether the components in the transmitting coil are normal by monitoring the abnormal standing wave ratio of the transmitting coil. Even if the component is damaged, it cannot be monitored in time. If the transmitting coil sparks and the standing wave ratio remains unchanged, the transmitting coil may be burned through, thereby endangering the safety of the patient.

The invention provides magnetic resonance imaging equipment and a monitoring method thereof. The magnetic resonance imaging equipment comprises a magnet device, a photoelectric detector and a controldevice. The magnet device comprises a main magnetic field coil, a gradient coil and a radio frequency transmitting coil, the gradient coil is arranged on the inner side of the main magnetic field coil, and the radio frequency transmitting coil is arranged on the inner side of the gradient coil. The photoelectric detector is arranged between the gradient coil and the radio frequency transmitting coil, and comprises a sensing end which faces the radio frequency transmitting coil and is used for sensing an optical signal generated by the radio frequency transmitting coil and outputting a corresponding electric signal. And the control device is electrically connected with the photoelectric detector and the magnet device, and is used for receiving the electric signal and controlling the radio frequency transmitting coil to stop transmitting when receiving the electric signal. Through the arrangement, the sensing end of the photoelectric detector is used for sensing the optical signal generated by the radio frequency transmitting coil, and compared with the related art, the photoelectric detector can sense the abnormal state of the radio frequency transmitting coil in real time, and is safe, timely, simple and reliable.
Description
technical field [0001] The present application relates to the technical field of medical imaging, in particular to a magnetic resonance imaging device and a monitoring method thereof. Background technique [0002] Magnetic resonance imaging (Magnetic resonance imagine, MRI) technology uses hydrogen nuclei (protons) in human tissue to be excited by radio frequency pulses in a magnetic field to generate nuclear magnetic resonance, generate nuclear resonance signals, and reconstruct a certain level of the human body through electronic computer processing. image imaging technology. Magnetic resonance imaging equipment is an imaging equipment based on magnetic resonance imaging technology. It is a kind of tomographic imaging. It has the advantages of high image resolution, comprehensive examination, and non-invasiveness. Therefore, it has been widely used in the field of medical imaging. [0003] The magnetic resonance imaging equipment is extremely complicated. The transmitting...
