Abstract

The invention provides a shimming strip and an assembling and disassembling device thereof. The assembling and disassembling device comprises a guide protection mechanism and a handle. The guide protection mechanism is used for leading the shimming strip into a shimming groove, and the handle is used for controlling the shimming strip to move in the guide protection mechanism. The guide protection mechanism is provided with a connecting structure, and the connecting structure is located at one end of the guide protection mechanism and used for being connected with the shimming groove. The handle and the guide protection mechanism are matched to form a self-locking structure. Through the assembling and disassembling device of the shimming strip, technical staff in the field can assemble and disassemble the shimming strip quickly, simply, conveniently and safely without conducting field lowering / field rising operations, and therefore the uniformity of a magnetic field of a system is improved and maintained. Moreover, the assembling and disassembling device is simple in structure, easy to realize, safe and convenient to use.

Description

technical field [0001] The invention relates to magnetic resonance imaging technology, in particular to a shim strip and a loading and unloading device thereof. Background technique [0002] In an existing magnetic resonance imaging system, a magnet is used to generate a magnetic field, and then the magnetic field is used to perform magnetic resonance imaging. Specifically, in an MRI system, a magnet is required to generate a highly uniform magnetic field in the image acquisition field (FOV) for MRI. Superconducting magnets usually have a ring-shaped columnar structure. Due to the distance from the center of the superconducting magnet, the magnetic field strength in different regions is usually different. Therefore, it is necessary to take certain measures to correct the uniformity of the magnetic field in different regions, so that Obtain magnetic resonance images with better imaging quality. [0003] In the prior art, a method of passive shimming is usually used to make ...
