Embodiment Construction

[0013] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0014] Such as Figure 1-Figure 2 As shown, a special-purpose MRI gradient coil according to the present invention is specially used for male prostate, reproductive system or female abdominal cavity inspection. Convenience, including the main coil 2 and the shielding coil 3, the main coil 1 and the shielding coil 3 are arranged diagonally, which reduces the eddy current, can greatly improve the performance of the system, and the imaging quality is further improved. There is a FOV at the center Space 4, using the current general-purpose superconducting magnet, reduces the difficulty of research and development, and the system cost is also greatly reduced. FOV space 4 ensures the imaging area of ​​the dedicated system, high stability, and its high ...

Abstract

The present invention provides a special MRI gradient coil. The gradient coil body has a saddle-shaped structure as a whole, including a main coil and a shielding coil. The main coil and the shielding coil are arranged diagonally, and a FOV space is provided at the center. The beneficial effect of the present invention is that the design of the coil is based on a saddle-like structure, which is open and easy to apply; especially this MRI gradient coil uses the current general superconducting magnet, which reduces the difficulty of research and development and greatly reduces the system cost; The high gradient switching rate meets the needs of fast imaging, and at the same time has low peripheral nerve stimulation; using MRI to examine the reproductive system greatly improves the safety of the examination.

Description

technical field [0001] The invention relates to the technical field of gradient coils in the technical field of MRI, in particular to a special-purpose MRI gradient coil. Background technique [0002] Magnetic Resonance Imaging (MRI) technology integrates modern electromagnetics, atomic physics, quantum mechanics, biochemistry and modern digital signal processing technology, and is one of the concentrated manifestations of the high development of modern science and technology and the high civilization of human society. Compared with other medical imaging methods, magnetic resonance imaging has the characteristics and advantages of high speed, high resolution, multi-parameter and multi-contrast, no invasive injury, and no radiation. Magnetic resonance imaging technology has become one of the most important inspection methods in clinical medicine, and has made great contributions to the cause of human health, so it has important clinical application value in medical inspection...
