Description

technical field [0001] The invention relates to the technical field of medical magnetic resonance systems, in particular to a large aperture interventional magnetic resonance system. Background technique [0002] Interventional magnetic resonance uses magnetic resonance guidance devices as interventional guidance tools. Magnetic resonance has incomparable advantages over other imaging methods. Its tissue contrast is excellent, and the spatial resolution reaches submillimeter level. It is beneficial to lesion localization and interventional guidance, and more importantly. The most important thing is that magnetic resonance has the ability of multi-plane and three-dimensional volume reconstruction, which can comprehensively evaluate the important anatomical relationship between the intervention target and adjacent tissues. Physicians should be able to approach patients at any time during interventional surgery. The emergence of open magnet technology and the advancement of rap...

Problems solved by technology

[0003] At present, the information collected for the diagnosis of internal human diseases is mainly through B-ultrasound and CT. Ionizing radiation and other advantages, but subject to technical safety issues such as imaging speed, navigation technology, and magnetic compatibility of auxiliary equipment and consumables in the operating room, it has not been able to be applied to minimally invasive treatment under magnetic resonance. With the advantages of precise treatment, good curative effect, and small side effects, it has become a new diagnostic method comparable to surgery, chemotherapy and radiotherapy. Therefore, the need for the above-mentioned interventional magnetic resonance system is imminent.
