Magnetic resonance scanning imaging method and system

Abstract

The invention discloses a magnetic resonance scanning imaging method and system. The method includes: performing level planning for the range to be scanned; the level planning includes: setting a single positioning frame for the range to be scanned, setting the number of local scanning steps, and setting the local area of ​​each step in the single positioning frame. The scanning range and the local scanning center position, the local scanning range is smaller than the shimming area range, and each local scanning range is superimposed to cover the range to be scanned; according to the local scanning steps in the layer planning, the beds carrying patients are moved sequentially , so that the local scanning center position of each step corresponds to the center of the shimming area, perform isocentric scanning on the local scanning range of each step, and obtain local magnetic resonance data; resonance image. The system includes: a scanning planning module, a patient positioning system, a magnetic resonance scanning component and a control system, and an image processing module. The operation process of the present invention is simpler.

Description

technical field [0001] The invention relates to the field of medical imaging, in particular to a magnetic resonance scanning imaging method and system. Background technique [0002] At present, Magnetic Resonance Imaging (MRI), as a computer imaging technology that integrates research results in multiple fields such as physics, chemistry, biology, and medicine, has been widely used in medical imaging examinations. The basic principle is: according to the different attenuation of the released energy in different structural environments inside the material, a high-frequency alternating electromagnetic field is added on the basis of a uniform magnetic field, and by detecting the resonant absorption phenomenon of the high-frequency electromagnetic field, it is known that the composition of this The position and type of the nucleus of the object can be used to draw the internal structure image of the object. [0003] Large-scale transverse scans (eg, whole-body diffusion-weighte...

Problems solved by technology

[0006] However, in the process of realizing the present invention, the inventor found that no matter it is the prior art of the first multi-protocol multi-location frame or the second prior art of the single-protocol multi-location frame, there are the following problems: Once one of the positioning frames changes, the other positioning frames must also be adjusted adaptively, the operation process is cumbersome, and the operation process is particularly dependent on the operator's own experience.
