Magnetic resonance imaging device

Abstract

The invention discloses a magnetic resonance imaging device. The magnetic resonance imaging device is provided with a magnetism-compatible display screen. The display screen is suitable for the magnetic-field distribution of the magnetic resonance imaging device, influence on the magnetic-field distribution of the magnetic resonance imaging device is reduced, magnetic resonance imaging will not be affected, and therefore a good imaging effect can be achieved. Furthermore, by means of playing video information, the attention of a patient can be effectively shifted when the patient is under magnetic resonance check, the feared state of mind can be eliminated, and the comfortableness can be improved. Specific picture or video information played on the display screen can effectively stimulate the brain and facilitates human body brain function imaging research work. Because a sliding rail is arranged on the inner wall of a check region of the magnetic resonance imaging device, the position of the display screen can be adjusted according to the position of the patient, and the patient can more comfortably see the video information displayed on the display screen. Because a darkroom is arranged between optical fibers and a projection device, influence of outside parasitic light can be avoided, light dispersing is avoided, and video signal quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a magnetic resonance imaging device. Background technique [0002] Generally, a medical imaging device is a device configured to provide an image by obtaining information of a patient. Medical imaging devices include x-ray devices, ultrasound diagnostic devices, computer tomography devices, and magnetic resonance imaging devices. Among the medical imaging devices described above, magnetic resonance imaging devices provide images with various diagnostic information and strong contrast while allowing relatively free conditions for image capture, thereby occupying an important position in medical image diagnosis. [0003] Magnetic resonance imaging (MRI) refers to obtaining images of the density and physiochemical characteristics of atomic nuclei by using a magnetic field that is harmless to the human body and radio frequency (RF) as non-ionizing radiation to generate n...
