Description

Magnetic resonance radio frequency coil

【Technical field】

The utility model is related to medical instruments field, more particularly to magnetic resonance radio frequency coil.

【Background technology】

Magnetic resonance imaging (MRI) technology is to be applied to the important technology that hospital clinical is diagnosed.And radio-frequency coil is to realize to be somebody's turn to do The important device of technology.At present, there is such class radio-frequency coil 10, such as Fig. 1, their concentrated expressions go out following characteristics：

(1) by the way of being kept completely separate using top 11, bottom 13, to concede enough spaces, to insert patient's needs The position of diagnosis；

(2) unlatching and locking of top 11, bottom 13 are realized using both sides contact switch；

(3) top 11, the signal of bottom 13 are realized using (with the contact pin or jack) grafting of terminal 15 of cable is connected with Connection.

Such radio-frequency coil basic operational steps are as follows：

Step S1：Radio-frequency coil 10 is fixed on base；

Step S2：Personnel stand on side (this is sentenced exemplified by left side), with the hands trigger switch 17, by top 11 with Portion 13 is separated；

Step S3：Both hands hold up top 11, are placed in another location, then need the position being imaged to be placed in bottom patient Within 13；

Step S4：Both hands hold up top 11, and calibrating position connects on top 11 with bottom 13, is in radio-frequency coil 10 Closure state.

Learn that existing such coil leaves row deficiency by putting into practice to use：
