The coils of traditional coil imaging devices are usually distributed at various positions of the imaging device to facilitate all-round and multi-angle imaging of the patient's body. This form makes the space occupied by the coil installation larger, resulting in a larger volume of the coil imaging device. In addition, during the imaging process of the traditional coil imaging device, the magnetic fields of adjacent coils are also prone to affect each other, and cross-coupling between coils is prone to occur, so it is still necessary to improve.
