Specific embodiment
The application is described in further detail below by specific embodiment combination attached drawing.
As shown in Figures 1 to 4, the magnetic resonance radio frequency coil of the application, a kind of embodiment, including connector 10 and line
Module 20 is enclosed, coil module 20 has multiple.Coil module 20 includes shell 21, interconnecting piece and radio-frequency coil 22, radio-frequency coil 22
It is arranged in shell 21, interconnecting piece setting can be slided on connector 10 in 21 coil module 20 of shell by interconnecting piece, root
According to position of the imaging region adjustment coil module 20 on connector 10 so as to adjust the position distribution of coil module, to realize sense
The imaging in interest region.Connector 10 includes flexible flexible cable in one embodiment.I.e. connector 10 can basis
It needs to bend forming, slides coil module 20 on connector, to better cover the portion that human body or animal body need to be imaged
Position.Rope, cable etc. can be selected in connector 10.Interconnecting piece can be ring, such as connection ring 23 or connection sleeve 24.Even
Fitting 10 can be threaded through in connection ring 23 or connection sleeve 24.
In another embodiment, connector 10 may include guide rail (not shown).Interconnecting piece includes cooperating with guide rail
