Description
Technical field
The present invention relates to medical magnetic resonance technical field, especially relate to a kind of visual presentation system for magnetic resonance examination.
Background technology
Medical nuclear magnetic resonance imaging technology (MRI) is a kind of relatively conventional imaging technique at present, utilizes the principle of magnetic resonance to obtain the detailed structure chart of patient.General magnetic resonance system comprises: the very uniform magnetic field system of high field intensity, for generation of the gradient fields system of variable magnetic field, and radio frequency (RF) transmitter receiver system, and computer disposal imaging system etc.The change of the gradient magnetic when nuclear magnetic resonance, the distribution leading human body internal magnetic field changes along with the change of locus, reaction can be produced to different radiofrequency signals like this at the hydrogen atom of human body diverse location, by receiving this reaction, and computing in addition, the information of hydrone in spatial distribution can be obtained, thus obtain the structure of inside of human body.
FMRI (functional MRI) is based on mr techniques, and allow observer can observe a kind of advanced technology of subjects's brain function activity, it achieves the visual of human thinking first.Its principle utilizes blood oxygen saturation to rely on effect (blood oxygenation level dependent, BOLD), makes the cerebral tissue imaging in magnetic resonance be in activity.The dynamic cerebral activity change that the thinking activities that Belliveau in 1991 etc. use this technology to see human brain first on screen causes, thus make the mankind enter the epoch of drawing thinking collection of illustrative plates.From then on, fMRI technology becomes the primary tool of brain science research, and the research for this technology once obtained Nobel Prize (physics, chemistry, medical science and physiology are encouraged) for 6 times.The common research method of fMRI uses special visual stimulator to coordinate special-purpose software (E-prime, Matlab etc.) give subjects and specifically stimulate, signal intensity when simultaneously observing stimulation with magnetic resonance imaging in human brain, then mathematically analytic signal, obtains brain activation map picture.
The shortcoming that existing scheme exists: it is less that subjects watches visual angle, due to the structure that magnetic resonance is special, the display terminal of existing display system need be positioned over outside magnetic resonance cavity, 50cm is greater than with subjects's distance, cause subjects to watch visual angle and be less than 30 degree, the content on viewing display device can not be concentrated on.And fMRI research needs to give subjects feeling of immersion, this display device be placed in outside magnetic resonance cavity cannot provide real feeling of immersion.Existing scheme realizes complicated, and due to the special environment of magnetic resonance, the image transmitting of existing scheme and display mode all more complicated, bulky, debugging is before the use complicated.
