Abstract

The embodiment of the invention provides a model generation method, a magnetic resonance imaging scanning method and a system. The method includes the steps of receiving the magnetic resonance scanning positioning image and coil information of the designated part, extracting the specified characteristic information from the received information, a match category is determined base on that specified feature information, based on the MRI scanning and localization model of the specified position corresponding to the matching category, obtaining positioning information corresponding to a magneticresonance scanning positioning image to be processed, in accordance with location information, performing an imaging scan operation on a designated area, using the model trained by neural network, automatically obtaining positioning information, so as to automatically perform positioning operation based on the positioning information. The manual operation is reduced, not only the positioning timeis shortened, the processing efficiency of the magnetic resonance imaging scanning is improved, but also the human resources are saved, the human cost is reduced, and the problem that the magnetic resonance imaging scanning processing efficiency is low and the human cost is high in the prior art is solved to a certain extent.

Description

【Technical field】 [0001] The solution relates to the technical field of medical imaging, in particular to a model generation method, a magnetic resonance imaging scanning method and a system. 【Background technique】 [0002] In MRI examination, in order to achieve the best examination results, it is generally necessary to scan the scout image first, adjust the scanning position and rotation angle on the scout image, that is, positioning, and then perform a formal clinical scan. [0003] In the prior art, the doctor manually adjusts the positioning frame on the pre-scanned magnetic resonance scan positioning image, and manually performs the positioning operation for the next scan. This method requires more manual operations and cannot automatically complete the positioning. The positioning frame must be adjusted for each scan. In this way, during the MRI scanning process, the physician needs to perform positioning operations repeatedly, which is time-consuming and labor-intens...
