Embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast description of drawings embodiment of the present utility model.Wherein, identical parts adopt identical label.
What Fig. 2 showed is according to a kind of synoptic diagram that is used for the head coil of magnetic resonance system of the present utility model.Described magnetic resonance system can be an a kind of open type magnetic resonance system, and for example C type magnetic resonance system perhaps also can be a kind of closed system, for example magnetic resonance system as shown in Figure 2.This system generally includes movably bed board 2 of a magnet 1 cylindraceous and, and this magnet 1 has one and checks space 3, and described bed board 2 can promote it by the drive unit (not shown) and move to the described inspection space 3 outside described magnet 1.
State when Figure 2 shows that magnetic resonance system work, the person of being scanned is flat on the bed board 2, and covers head coil 5 at the person's of being scanned head 4.Fig. 3 is the schematic perspective view according to head coil 5 of the present utility model, has wherein omitted image display 6.As shown in Figure 3, this head coil 5 comprises: a housing 51, this housing 51 has the profile with human body head profile phase coupling, comprise on the described housing 51 and a plurality ofly be arranged in the housing 51 or the coil unit 52 on the housing 51, in the position of described housing 51 tops over against the person's of being scanned eye 41, be provided with a form 53, be used to install an image display 6.
Fig. 4 is the cross sectional view according to head coil 5 of the present utility model, as shown in Figure 4, this head coil 5 comprises described image display 6, this image display 6 is arranged in the described form 53 on the above-mentioned housing 51, described image display 6 can be a LCD, certainly, it will be appreciated by those skilled in the art that this image display 6 also can be a cathode ray tube (CRT) display.But,, adopt LCD littler to the person's of being scanned eye injury for the utility model.
Referring again to Fig. 2-4, according to head coil 5 of the present utility model also comprise one can the described image display 6 of remote control control device 7, described control device 7 can comprise a hand held controller 71 (referring to Fig. 2), a media player (not shown) and a monitor (not shown), this monitor can show the content that sends described image display 6 to synchronously.Described hand held controller 71 can be controlled the content that described media player transmits to described image display 6.Described hand held controller 71 can be the cable controller that connects in wired mode, also can be Digiplex, for example Infrared remote controller.
Below the operation according to head coil of the present utility model is further detailed.
When needs carried out magnetic resonance examination or research to the person of being scanned, the person of being scanned was flat on the bed board 2, and covered described head coil at the person's of being scanned head.The image display of described head coil links to each other with remotely controlled plant 7 by connection line.
When need be when the person of being scanned transmits specific content (literal, picture or video) by image display 6, operating personnel can send instruction to described media player by the hand held controller 71 of described control device 7, and described media player selects content corresponding to send image display 6 to by the instruction that receives from wherein hard disk or CD.
In order to monitor the content that sends the person of being scanned to, described media player also can send identical content synchronization to monitor.
In addition, in some research process, if desired be not scanned person oneself and be chosen in content shown in the image display 6, also can be by the described hand held controller 71 of the person of being scanned oneself operation, in this case, this hand held controller 71 is that an infrared controller or other wireless controller may be more more convenient.
According to head coil of the present utility model, owing to have an image display, LCD for example can make that extraneous visual information is very convenient to pass to the person of being scanned accurately, for a lot of magnetic resonance applications provide convenience.Needed two researchers in the past, a researcher gives various visual signals to the person of being scanned, another researcher's scanning imagery, there has been image display can be directly finish to signal and two work of scanning, and avoided the visual information that reason causes because myopia or object putting position be not good etc. to transmit inaccurate by a researcher.
Common head coil is in order to keep the structure of optical window meeting limit shell, thereby the position of antenna and size in the restriction head coil, cause the reduction of magnetic resonance receive signals noise ratio, adopt image display use can complete closed shell, thereby the design that makes the head coil inside antenna more flexibly effectively.
The person's of being scanned hand held controller can be checked the information that oneself needs easily, can loosen the person's of being scanned mood by some special visual informations, alleviates its psychological pressure.
Further, scanning person also can be on one's sick bed with the own scanning to oneself of hand-held control image display direct control system's realization.
The above only is the schematic embodiment of the utility model, is not in order to limit scope of the present utility model.Any those skilled in the art, equivalent variations, the modification of being done under the prerequisite that does not break away from design of the present utility model and principle and combining all should belong to the scope of the utility model protection.
