Problems solved by technology

[0003] The existing traditional gradient coil structure uses the hollow Z main coil and Z shielding coil as the cooling channel. In order to reduce the influence of eddy current, the diameter of the coil should not be too large, which will affect the heat dissipation effect. If different connection methods are used to meet the heat dissipation requirements , will form too many joints, increasing the probability of water leakage. At the same time, the biggest problem of this coil is that it cannot realize the separation of water and electricity. To ensure the safety of patients, deionized water must be used, which increases the difficulty and cost of maintenance.
The patent is ZL201420289868.3 "An Active Shielding Gradient Coil Structure". The structure proposed in this patent improves the heat dissipation capability of the gradient coil by sacrificing the performance of a part of the Z coil. However, this design does not consider many technological difficulties in the manufacturing process. Consider the user's requirements for radio frequency shielding and shimming space, as well as the impact of the coil based on this structure on the uniformity of the magnetic field

Description

Technical field: [0001] The invention belongs to the technical field of MRI gradient coils, in particular to a gradient coil using composite cooling water pipes. Background technique: [0002] The gradient coil is one of the core components of the MRI (Magnetic Resonance Imaging, English full name: Magnetic Resonance Imaging) system, which mainly realizes frequency encoding, phase encoding and layer selection during the MRI scanning process. [0003] The existing traditional gradient coil structure uses the hollow Z main coil and Z shielding coil as the cooling channel. In order to reduce the influence of eddy current, the diameter of the coil should not be too large, which will affect the heat dissipation effect. If different connection methods are used to meet the heat dissipation requirements , will form too many joints, increasing the probability of water leakage. At the same time, the biggest problem of this coil is that it cannot realize the separation of water and ele...
