Background technology
Functional MRI experiment is the scientific experiments research of carrying out under special experimental situation, due to the particularity of experimental situation, require experiment to stimulate display device to there is the characteristic that is different from general psychology, clinical medicine experimental facilities, but meanwhile, this type of experimental facilities must have again accuracy and the practicality under general experimental situation.Therefore, in functional MRI experiment, all integral component can not produce any Radio frequency interference, especially be positioned at the parts of scanning room (magnet bore), this causes magnetic resonance EPI sequence generation radio frequency artifact, when serious, even can cause common clinical sequences to produce artifact, affect normal clinical scanning.。
At present, conventional display mode is, experiment image is mapped in outside magnet bore in the mode of projection, and the experimenter in magnet bore watches image information by reflecting mirror group.But because projection definition is not high, add image and be subject to the impact of mirror group reflectance in reflection process, image can fuzzy distortion.And because the time of utilizing functional MRI to test is conventionally longer, experimenter is easily sleeping in magnet bore, and the healthy of experimenter exerted an influence.
Utility model content
The purpose of this utility model is to provide the image display system using in a kind of magnetic resonance, this image display system can adopt and be arranged in magnet bore or the magnetic compatible display on magnet bore side shows experiment image, greatly improve the definition that experimenter sees image, and by the magnetic compatible processing to magnetic compatible display, shielding processing, make display not produce Radio frequency interference, and utilize optical fiber remote distance video transfer signal, further reduce generation Radio frequency interference possibility, improved the signal to noise ratio of video signal.
To achieve these goals, the image display system using in a kind of magnetic resonance of this utility model, described image display system comprises magnetic compatible display, receives control box, master console and computer;
Described master console is for receiving the picture signal of the experiment image that described computer sends, and converts picture signal to fiber-optic signal and be sent to described reception control box, and master console provides power supply for receiving control box simultaneously;
Described reception control box is used for receiving the fiber-optic signal that master console sends, and fiber-optic signal is reduced into picture signal, presents image by described magnetic compatible display;
Wherein, magnetic compatible display is arranged in magnet bore or magnet bore side, and magnetic compatible display is covered with the screen layer of electromagnetic shielding, and its inner member is that nonmagnetic substance is made.
Further, described magnetic compatible display is LCD display.
Further, between described reception control box and described master console, on connecting power line and fiber-optic signal line, be coated with electro-magnetic screen layer.
Further, on described magnetic compatible display, be provided with image collecting device, described image collecting device connects described reception control box, described master console and graphical display successively, the picture signal of collection is sent to reception control box by image collecting device, reception control box converts picture signal to fiber-optic signal and is sent to master console, fiber-optic signal is reduced into picture signal by master console, and demonstration gathers image in graphical display, by image collecting device, can observe the situation in magnet.
Further, be connected with described computer by wireless signal for the wireless reaction handle that records described experimenter's feedback operation.
