Title:
FLEXIBLE RADIO FREQUENCY SHIELDING DOOR AND MAGNETIC RESONANCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/242475
Kind Code:
A1
Abstract:
A flexible radio frequency shielding door (10) and a magnetic resonance device (20). The flexible radio frequency shielding door (10) comprises: a shielding support (110) and a door frame assembly (120); the shielding support (110) comprises a first base (112) and a second base (114); the first base (112) is fixed to the magnetic resonance device (20); the second base (114) is fixedly connected to the first base (112); the door frame assembly (120) comprises a first side (120a) and a second side (120b); the first side (120a) is fixedly connected to the first base (112); the second side (120b) is abutted against the second base (114); the second side (120b) is rotatable with respect to the first side (120a) such that the door frame assembly (120) can be folded and unfolded: when the door frame assembly (120) is folded, the flexible radio frequency shielding door (10) is opened, and when the door frame assembly (120) is unfolded, the flexible radio frequency shielding door (10) is closed; and a shielding member is provided at a position on the shielding support (110) corresponding to the joint between the shielding support (110) and the first side (120a) and/or the second side (120b) to shield radio frequency at the joint between the shielding support (110) and the door frame assembly (120). The magnetic resonance device (20) comprises a magnet (210) and the flexible radio frequency shielding door (10). The magnet (210) is provided with a scanning channel; and the flexible radio frequency shielding door (10) is arranged corresponding to the scanning channel and is fixed to the magnet (210). The flexible radio frequency shielding door (10) has a simple structure, a large viewing field, fewer components, and can easily achieve a good radio frequency shielding effect.
