Problems solved by technology

[0006] To sum up, this neck motion MRI control method is cumbersome and inefficient, and the adjustment range of the curvature of the subject’s neck cannot be precisely controlled and cannot be adjusted at will, and the accuracy of position repeatability is not good. High, so the efficiency and accuracy of its motion imaging cannot be guaranteed

Abstract

The present invention provides a motion magnetic resonance imaging control device used for adjusting the imaged position bending degree of a checked object. The invention comprises a bracket that revolves around a rotation axis and the bracket supports the imaged position of a checked object; an interlinkage piece that is fixedly connected with the bracket; and a driving source for driving the interlinkage piece to cause the bracket to revolve around the rotation axis. The magnetic resonance system uses the motion magnetic resonance imaging control device for imaging a motion; especially whenimaging and scanning a neck motion, the neck bending degree and the position of the checked object can be controlled in real time. On the basis of actual need, a doctor can manually (or activate a corresponding order on a control equipment) control the driving source for precisely and gradually changing a checked object neck bending degree within an adjusting range; or on the basis of actual need, the doctor precisely sets a checked object neck bending degree, and precisely reverts to any neck bending status when necessary.

Description

technical field [0001] The invention relates to a magnetic resonance imaging device, in particular to a motion magnetic resonance imaging control device. Background technique [0002] Magnetic resonance motion imaging, especially cervical motion magnetic resonance imaging, provides a method for functional determination of the cervical spine, which can be used in the diagnosis of position-dependent lesions, spinal cord stenosis, occult dislocation, or other types of functional lesions in the occipital and cervical spine. , is a classic evaluation criterion for qualitative judgment. [0003] In cervical motion magnetic resonance imaging, qualitative and positioning information can be obtained by accurately displaying the relationship between the spinal cord, intervertebral disc, and vertebral body. Anomalies found. [0004] When performing neck motion magnetic resonance imaging on the subject, due to the influence of the anatomical structure, doctors often need to repeatedly...
