Problems solved by technology

Among them, the improvement of MRI hardware facilities can be achieved by designing open magnets, increasing the area between magnets, and improving the illumination between magnets, etc., but it is difficult and costly
Psychological care and adaptive training take a long time and are inefficient
The effect of sedative examination is good, but most patients are unwilling to accept it, and it is difficult to grasp the time of falling asleep, which also affects the examination of MRI

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings.

[0022] Virtual reality (Virtual Reality System, VR) is to use computer simulation to generate a three-dimensional virtual world, providing users with simulations of vision, hearing, touch and other senses, so that users can experience real-time, unlimited Observe things in three-dimensional space. It can be used to help patients overcome phobias and assist patients to complete MRI examinations. However, due to the influence of the strong magnetic field of MRI, no metal and electrical devices can be placed in the MRI examination room. The VR playback system needs to be placed outside the nuclear magnetic examination room because it contains electronic devices, and it cannot use any metal medium for conduction during its information transmission process.

[0023] Such as figure 1 As shown, a magnetic resonance compatible image transmission and display device of the pr...

Abstract

The invention discloses a magnetic resonance compatible image transmission and display device. The device comprises PC machine, a projector, a front objective group, an image transmission fiber optics bundle, a relay objective group, a projection image surface and an ocular group which are sequentially arranged from left to right; an image terminal, from which a virtual reality scene is outputted, is constituted by the PC machine and the projector; both the image terminal and the front objective group are arranged outside a nuclear magnetic resonance examination room; the relay objective group, the projection mirror surface and the ocular group are arranged in a nuclear magnetic imaging magnet cavity in the nuclear magnetic resonance examination room; and a dynamic image, which is generated by virtue of the image terminal, is transmitted from the exterior of the nuclear magnetic resonance examination room to the interior of the nuclear magnetic resonance examination room by virtue of the front objective group, the image transmission fiber optics bundle and the relay objective group, and the dynamic image on the projection image surface can be observed by human eyes through the ocular group. The device provided by the invention has a function of relieving or eliminating claustrophobia in a patient through the virtual reality scene, so as to bring about benefit for the patient to accept MRI examination smoothly.

Description

technical field [0001] The invention relates to an auxiliary device for magnetic resonance examination, and more specifically relates to a magnetic resonance compatible image transmission and display device. Background technique [0002] Magnetic Resonance Imaging (MRI) is an important clinical imaging tool. Claustrophobia is a kind of psychological disorder. Due to the narrow and airtight space of most existing MRI equipment, it is easy to cause tension and fear in patients, induce the onset of claustrophobia in patients with claustrophobia, affect the quality of MRI imaging, and even lead to inspection failures. was forced to interrupt. Therefore, how to alleviate or eliminate the patient's claustrophobia and help the patient successfully complete the MRI examination is a technical problem to be solved urgently by those skilled in the art. [0003] At present, commonly used methods to improve the success rate of MRI examinations for patients with claustrophobia include i...
