Abstract

The embodiment of the invention provides a magnetic resonance calibration scanning sequence configuration and image obtaining method and system, and relates to the medical image technology field. The method provided by the embodiment of the invention comprises: obtaining one-dimensional projections of an interested region on at least two directions according to a measurement sequence to determine the lengths of the interested region on the at least two directions; or, obtaining the images of the interested region according to the measurement sequence to determine the lengths of the interested region on the at least two directions; and determining the scanning range of a calibration scanning sequence based on the lengths. The scanning area corresponding to the interested region is subjected to system calibration to reduce the time of the system calibration and improve the efficiency of the system calibration.

Description

【Technical field】 [0001] The present invention relates to the technical field of medical imaging, in particular to a method and system for magnetic resonance calibration scanning sequence configuration and image acquisition. 【Background technique】 [0002] In order to make the images obtained by clinical scanning clearer, it is necessary to calibrate the magnetic resonance scanning system before performing clinical scanning on the scanning object. In the existing system calibration method, the calibration scan sequence used for system calibration is fixed, and the calibration scan sequence corresponds to the entire imaging space of the magnetic resonance system, and the calibration of the magnetic resonance system takes a long time. In addition, in order to reduce the scan time of the calibration scan sequence as much as possible, only lower resolution calibration data can be collected, resulting in low quality of the magnetic resonance image obtained by the final magnetic r...
