The invention relates to a magnetic resonance multi-antenna radio frequency transmission device and a magnetic resonance system, which belong to the technical field of medical equipment. The magnetic resonance multi-antenna radio frequency transmission device includes a radio frequency receiving coil and a radio frequency receiving device. The radio frequency receiving coil in the magnetic resonance equipment can collect The magnetic resonance signal excited during magnetic resonance detection, the radio frequency receiving coil can send the magnetic resonance signal to the radio frequency receiving device wirelessly, the radio frequency receiving device includes multiple antennas and radio frequency receivers, and multiple antennas can forward the magnetic resonance signal to the radio frequency receiver The machine and the radio frequency receiver analyze the magnetic resonance signal. To transmit magnetic resonance signals wirelessly, due to the shielding used in the special strong magnetic field structure of magnetic resonance equipment, multipath effects will occur when transmitting signals, which will affect the reception performance. In this scheme, the use of multi-antenna reception can improve Receive efficiency, and avoid the use of radio frequency lines to transmit signals, simplify work flow, and reduce the cost of laying cables.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to a magnetic resonance multi-antenna radio frequency transmission device and a magnetic resonance system. Background technique [0002] Nuclear Magnetic Resonance Imaging (NMRI), also known as spin imaging (spin imaging), also known as magnetic resonance imaging (MRI), is the use of nuclear magnetic resonance principles, according to the released energy in different structural environments inside the material The different attenuation in the object is detected by applying a gradient magnetic field to detect the emitted electromagnetic wave, and the internal structure image of the object is obtained according to the electromagnetic wave. [0003] The magnetic resonance system mainly includes several subsystems of magnet, gradient coil, radio frequency coil, and receiving chain. A uniform static magnetic field is generated by the superconducting magnet, and the magnetic re...
