Abstract

The invention provides a magnetic resonance scanning trigger method and device. The method includes the steps that a respiration curve of a subject is acquired, wherein the respiration curve comprisesmultiple respiration sub-curves, and each respiration sub-curve corresponds to one respiration period; based on the respiration sub-curves, respiration gating parameters in magnetic resonance sequences for controlling scanning are determined, wherein the respiration gating parameters comprise image acquisition time and acquisition delay time; based on the magnetic resonance sequences comprising the respiration gating parameters, the subject is controlled to be scanned. By means of the technical scheme, motion artifacts caused by respiration motion of the subject can be effectively restrained,and high-quality magnetic resonance images are obtained.

Description

technical field [0001] The present application relates to the technical field of magnetic resonance, and in particular to a magnetic resonance scan triggering method and device. Background technique [0002] Magnetic resonance imaging (Magnetic Resonance Imaging, MRI) is one of the main imaging methods in modern medical imaging. Magnetic resonance imaging technology uses the signal difference of various tissues in the human body in a strong magnetic field environment to generate images to display the internal structure of the human body. Provides clinicians with multiple tissue contrast, high-resolution images. Generally, MRI requires a long scan time, in this case, when MRI is performed on the chest and abdomen of the subject, the respiratory movement of the subject will have an impact on the image quality of the final MRI image. Adverse effects, such as blurring of MRI images and motion artifacts. Therefore, how to suppress the motion artifacts caused by the subject's re...
