Problems solved by technology

[0005] The disadvantage of existing nuclear magnetic resonance imaging equipment is that the receiving coil must be quite close to the part to be tested in order to obtain the magnetic signal released by the part to be tested. Designing different kinds of receiving coils, on the other hand, increases the manufacturing cost of the equipment

Description

【Technical field】 [0001] The invention relates to the technical field of MRI imaging. 【Background technique】 [0002] The principle of the nuclear magnetic resonance (MRI) imaging system is to use a coil to detect the radio wave pulse energy absorbed and emitted by the spin of the atomic nucleus. The coil acts as a receiving coil and sometimes as a transmitting coil. With the help of pulses of energy from radio waves, an MRI scanner can locate a very small spot in a patient and then determine what type of tissue it is. The point might be a cube with sides only half a millimeter long. An MRI system scans a patient's body point by point to build a two- or three-dimensional map of tissue types. It then brings all the information together to create a 2D image or 3D model. The largest and most important component of an MRI system is the magnet. Magnets in MRI systems are measured in units called Teslas. The magnets used in MRI machines today have field strengths between 0.5 ...
