Abstract

The invention relates to the technical field of magnetic resonance, in particular to a radio frequency coil structure with conformal capacity for magnetic resonance imaging. The radio frequency coil structure with conformal capacity for magnetic resonance imaging comprises a coil rigid plastic shell and is characterized in that a plurality of through holes are evenly distributed in the outer edge of the coil rigid plastic shell; a plurality of channel modules are evenly distributed between the interior of the coil rigid plastic shell and the magnetic resonance imaging area, and the adjacent channel modules are connected in an overlapped mode. Compared with the prior art, the radio frequency coil structure which is used for magnetic resonance imaging and has the conformal capacity breaks through the limitation that the size of an imaging area of a traditional magnetic resonance rigid radio frequency coil cannot be changed, and the possibility is developed for more ingenious design and more flexible application of the magnetic resonance radio frequency coil.

Description

technical field [0001] The invention relates to the technical field of magnetic resonance, in particular to a radio frequency coil structure with conformal ability for magnetic resonance imaging. Background technique [0002] Magnetic resonance imaging is an advanced non-destructive imaging technology of the human body, which is widely used in the diagnosis of diseases in various parts of the human body. The magnetic resonance radio frequency coil is an important part of the magnetic resonance imaging system, and its performance directly determines the quality of the magnetic resonance imaging. [0003] According to the laws of physics, when the magnetic resonance radio frequency coil detects the magnetic resonance radio frequency signal emitted by the human body, the closer it is to the human body, the better. The traditional radio frequency coils are all hard coils, and the radio frequency loop formed by conductors, capacitors and inductors is directly attached to the har...
