The position of the mirror 210 relative to the rf coil 30 is adjusted by the adjusting module 300, so as to provide a better visual angle of light reflection according to the visual position of different patients, thereby effectively alleviating the feeling of claustrophobia of patients. Meanwhile, a better light reflection visual angle can be provided according to the visual positions of different patients and the placement positions of different visual stimulation devices, and effective visual stimulation is realized.

In the case where the support module 100 is placed directly on the scan bed 20, the stabilizing section 150 can be in direct contact with the scan bed 20, making the frame 10 more securely placed. Optionally, the side wall of the stabilizing part 150 that is matched with the scanning bed 20 is provided with a limiting protrusion 151 (see fig. 1), and the limiting protrusion 151 can be limited in a groove 20a (see fig. 3) on the scanning bed 20.
