Detailed description of the invention
The application is described in further detail in conjunction with accompanying drawing below by detailed description of the invention.
As shown in Figures 1 to 4, the magnetic resonance radio frequency coil of the application, its a kind of embodiment, including connector 10 and coil module 20, coil module 20 has multiple. Coil module 20 includes shell 21, connecting portion and radio-frequency coil 22, radio-frequency coil 22 is arranged in shell 21, connecting portion is arranged on shell 21 coil module 20 can be passed through connecting portion and slide on connector 10, the coil module 20 position on connector 10 is adjusted thus adjusting the position distribution of coil module, to realize the imaging of area-of-interest according to imaging region. Connector 10 includes flexible flexible cable in one embodiment. Namely connector 10 can bend shaping as required, makes coil module 20 slide on connector, in order to covering human body or animal body need the position of imaging better. Connector 10 can be selected for rope, cable etc. Connecting portion can be ring, as connected ring 23 or branch sleeve 24 etc. Connector 10 can be located in connection ring 23 or branch sleeve 24.
In another embodiment, connector 10 can include guide rail (not shown). Connecting portion includes the sliding shoe (not shown) coordinated with guide rail. Coil module 20 is slided in orbit by sliding shoe, in order to covering human body or animal body need the position of imaging better.
Described connector includes two, and coordinates with the connecting portion being arranged on cover top portion and outer casing bottom respectively.
In one embodiment, radio-frequency coil 22 includes channel radio frequency coil or a Multi-channel radio-frequency coil, specifically can be designed as required. If coil module can be a passage coil module, two channel line circle modules, triple channel coil module or more multichannel coil module.
The magnetic resonance radio frequency coil of the application, connecting portion is arranged on top and the bottom of shell 10, and connecting portion can also be arranged on other positions of shell 10. In one embodiment, connector 10 includes two, coordinates with the connecting portion being arranged on bottom shell 21 top and shell 21 respectively.
The magnetic resonance radio frequency coil of the application of the application, the shell 21 of its coil module 20 includes soft shell and/or rigidity shell, and namely coil module 20 can be soft shell, it is also possible to be rigidity shell, or a part is soft shell, another part is rigidity shell. The coil module of rigidity shell, is the inner surface that radio-frequency coil is produced on duricrust, and the coil module of soft shell, is be produced in flexible sheet by radio-frequency coil. Owing to rigidity shell can not arbitrarily bend, so its module interior loop spatial distribution of the coil module of rigidity shell is fixing. Flexible sheet can arbitrarily bend, so the spatial distribution of the coil module of soft shell is adjustable in, the coil module of soft shell can press close to human body surface according to practical situation when magnetic resonance acquisition signal.
For 8 passage carotid artery magnetic resonance radio frequency coil, three coil modules can be included, it is two 3 passage coil modules and 2 passage coil modules respectively, 3 modules are all enclosed within two tightropes, so, along this tightrope, the relative position of three modules just can change, because somebody's neck is thick, somebody is thin, if making 8 fixing passage coil carotid artery coils, perhaps somebody's neck coverage is good, but it is just bad that the neck of some people is likely to covering, after making this transportable module, the position of coil module can be adjusted according to neck thickness, be conducive to imaging better.
Above content is further description the application made in conjunction with specific embodiment, it is impossible to assert the application be embodied as be confined to these explanations. For the application person of an ordinary skill in the technical field, under the premise conceived without departing from the application, it is also possible to make some simple deduction or replace.
