Abstract
The invention relates to a large-aperture, short-cavity and superconducting magnetic resonance imaging (MRI) minimally invasive surgery platform system. Through the system, minimally invasive surgery treatment can be performed by means of the navigation of magnetic resonance imaging. By the adoption of the large-aperture, short-cavity and high-magnetic-field superconducting MRI technology, the bottleneck problems that in MRI minimally invasive surgery treatment, the quality of images is poor, the real time performance is poor, and the surgical space is narrow are solved. Through the short-cavity MRI technology, bidirectional minimally invasive surgery operation can be performed on the two sides of an MRI magnet, and the range of application of MRI to the minimally invasive surgery treatment is expanded. The large-aperture, short-cavity and superconducting magnetic resonance imaging (MRI) minimally invasive surgery platform system further has the fast blood flow imaging function, the diffusion coefficient imaging function, the temperature distribution imaging function, the MR perspective function and the MR endoscopy function besides the intraoperative sub-second super-fast imaging function. Compared with the existing X-CT, the large-aperture, short-cavity and superconducting magnetic resonance imaging (MRI) minimally invasive surgery platform system has the same minimally invasive surgery capacity as the X-CT, and moreover radiation hazards to medical staff and patients caused by X-rays are fundamentally eliminated.
