Embodiments of the present invention disclose a magnetic resonance receiving module, a hospital bed, and a receiving system of a magnetic resonance imaging system. The magnetic resonance receiving module comprises a system socket, an analog front end chip, and a packet unit; the system socket is disposed on the hospital bed of the magnetic resonance imaging system for receiving a down-converted magnetic resonance signal from a local coil; the analog front end chip is used for amplifying the down-converted magnetic resonance signal and converting the amplified magnetic resonance signal into adigital format; and the packet unit is used for encapsulating the magnetic resonance signal in a digital format into a data packet and sending the data packet to an imaging host. The embodiments of the present invention eliminate the need to transmit the magnetic resonance signal to a receiver via a radio frequency transmission line, thereby omitting the radio frequency transmission line and the receiver and thereout saving the cost and associated deployment of the radio frequency transmission line and the receiver.
Description
technical field [0001] The invention relates to the technical field of magnetic resonance imaging, in particular to a magnetic resonance receiving module, a hospital bed and a receiving system of a magnetic resonance imaging system. Background technique [0002] Magnetic resonance imaging (Magnetic Resonance Imaging, MRI) is a biomagnetic nuclear spin imaging technology developed rapidly with the development of computer technology, electronic circuit technology, and superconductor technology. It uses a magnetic field and radio frequency pulses to vibrate the precessing hydrogen nuclei (ie H+) in human tissue to generate radio frequency signals, which are processed by a computer and imaged. When an object is placed in a magnetic field, it is irradiated with appropriate electromagnetic waves to make it resonate, and then the electromagnetic waves released by it are analyzed, and the position and type of the atomic nuclei that make up the object can be known, and the precise in...
