Abstract
The invention provides a projection system for a magnetic resonance system. The projection system comprises a projector, a reflecting mirror, an image transmission optical fiber, a projection screen and a head coil reflecting mirror, wherein the projector is connected with the image transmission optical fiber; and the projector projects image information to the projection screen so that an examined patient views an image on the projection screen by the reflection of the head coil reflecting mirror. The projection system for the magnetic resonance system transmits the image to the screen whichcan be viewed by the patient in a reflecting way, and the patient can view different pictures during scanning, thereby preventing the fear and the boring mood of the patient during examination and providing visual simulation during brain function imaging.
Description
Technical field
The present invention relates to a kind of optical projection system, particularly about a kind of optical projection system that is used for magnetic resonance system.
Background technology
Existing nuclear magnetic resonance (MRI) system is made up of magnet system, general instrument system, the department of computer science graphical presentation system of unifying, and it has following advantage:
1, in all Medical Imaging means, the soft tissue contrast resolution of MRI is the highest, and it can clearly differentiate soft tissues such as muscle, tendon, fascia, fat; Distinguish the endocardium of higher signal, cardiac muscle and the visceral pericardium under high signal fat sets off and the pericardium of low signal of msp signal.
2, MRI has the ability that any direction is directly cut layer, and needn't change those who are investigated's position, in conjunction with the layer of cutting of different directions, can show the structure that is examined organ or tissue comprehensively, does not have the dead angle of observation.In recent years the volume scan of Application and Development, the real-time reconstruction of feasible various planes, curved surface or irregular tangent plane carries out the solid of anatomical structure or pathological changes easily and follows the trail of.
3, MRI belongs to no wound, no radiological survey X, has avoided image checks such as X line or radionuclide image by the damage due to the ray.MRI scanning is harmless.
4, the MRI imaging parameters is many, comprises to contain much information, and (spin echo SE) is example, and this technology can be obtained the image of three kinds of different in kinds: T1 weighting picture, T2 weighting picture and proton density weighting picture with most widely used spin echo.At present, kind surplus the known imaging parameters of MRI reaches ten is added the pulse train combination that surpasses hundred kinds, and many special Application of imaging technology, and the imaging potentiality of MRI are very huge, for clinical practice provides wide research field.
5, MRI has higher spatial resolution, although the spatial resolution of general MRI image is better than ultrasoundcardiogram and radionuclide image, near the level of DSA and CT not as good as X line plain film, X line angiocardiography.
After but those who are investigated are sent to this magnetic resonance imaging system, its sensation often with the complete isolated state in the external world, sometimes even produce the fear be difficult to describe, often cause checking failure or check that effect is bad.
Summary of the invention
