Abstract

The embodiment of the invention discloses a receiving coil module for a magnetic resonance imaging system, and a charging method. The receiving coil module comprises a radio frequency coil; a rechargeable power supply which can supply power to the radio frequency coil; and an induction coil which is used for generating the induced electromotive force for charging the rechargeable battery based on one main magnetic field and / or a gradient magnetic field of the magnetic resonance imaging system. According to the embodiment of the invention, the receiving coil module can employ the induced electromotive force generated by the induction coil for charging the rechargeable battery, and also can automatically control the on / off of the battery based on the induced electromotive force.

Description

technical field [0001] The invention relates to the technical field of magnetic resonance imaging, in particular to a receiving coil assembly and a charging method 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 interior of the object can be d...
