Description

technical field

[0001] The invention relates to a gradient coil production technology in the field of MRI technology, and provides an MRI gradient coil assembly platform and an assembly method. Background technique

[0002] Gradient coil is one of the core components of the MRI (Magnetic Resonance Imaging, English full name is: Magnetic Resonance Imaging) system. At present, only a few companies in the world have mastered its core technology. Only the British Tesla company and Nanjing Cichen Medical Technology Co., Ltd. are on the market. Ltd. sells mature gradient coil products.

[0003] As we all know, a magnetic field will be generated in the energized coil. Within a certain range, the magnetic field strength is proportional to the current passing through it. The main function of the gradient coil is to convert electrical energy into magnetic energy and provide the encoding magnetic field of the magnetic resonance system. Ideally, all electrical energy is converted into ...
