AI Technical Summary
Technical Problem
Existing localization scanning sequences lack automatic correction functions, resulting in a mismatch between the structural position and orientation in the image and the actual anatomical structure. Manual correction is inefficient and prone to errors.
Method used
The calibration sequence, including the shimming sequence, center frequency calibration sequence, and radio frequency power calibration sequence, is integrated into the positioning item scanning sequence. The calibration process is executed automatically, reducing manual intervention and improving calibration efficiency.
Benefits of technology
It achieves automated correction, saving time and manpower, improving imaging quality and efficiency, and ensuring image accuracy.

Abstract
The application provides a magnetic resonance imaging method and system with automatic correction function, and relates to the technical field of magnetic resonance imaging, and the method comprises the following steps: determining a positioning item scan sequence used for providing positioning information for imaging, and integrating a correction sequence before the positioning item sequence in the positioning item scan sequence; and performing scan positioning according to the positioning item scan sequence; wherein, the correction sequence is executed before the scan of the positioning item sequence, a correction result is obtained, and then the scan of the positioning item sequence is performed according to the correction result. Beneficial effects: by integrating the correction sequence into the positioning item scan sequence, an automatic correction process is realized, the need for manual intervention is reduced, time and human resources are saved, and the imaging quality and efficiency are improved.
