Magnetic resonance isolation device, magnetic resonance imaging equipment and control method of magnetic resonance imaging equipment

Abstract

The invention relates to a magnetic resonance isolation device, magnetic resonance imaging equipment and a control method of the magnetic resonance imaging equipment. The isolation device comprises a buffer part and a pressure sensor; the buffer part is provided with a main cavity, and the main cavity is configured to be used for charging and discharging a filling material to enable the buffer part to be in an expansion state or a contraction state; the pressure sensor is arranged on the front face of the buffer part; the front face of the buffer part is configured to be used for directly or indirectly making contact with a target object; and the pressure sensor is configured to be used for obtaining pressure information of the target object, and the pressure information is configured to be used as a basis for controlling the expansion degree of the expansion state. According to the isolation device, the buffer part can be in a contraction state before the target object enters the equipment to prevent the target object from entering into a barrier, and after the target object enters the equipment, the pressure on the target object is collected in the inflation process through auxiliary cooperation of the pressure sensor, so that the target object can be inflated. The expansion degree of the buffer part is controlled according to the body types of different target objects, so that the comfort of the target objects is improved.

Description

technical field [0001] The invention relates to the technical field of high-field magnetic resonance imaging, in particular to an isolation device for magnetic resonance, magnetic resonance imaging equipment and a control method thereof. Background technique [0002] In high-field MRI scanning, especially when the field strength is 3.0T, 5.0T and above, the higher SAR (specific absorption rate, specific absorption rate) will cause body burns to the target object (such as human body or animal), etc. Risk, because the closer to the inner wall of the VTC (Volume Transmitting Coil), the higher the SAR value, for the purpose of protecting the target object, it is a relatively simple and feasible method to isolate the part of the target object close to the inner wall of the VTC . [0003] At present, the most commonly used method is to use various cushions to isolate the target's arms, thighs and other parts that are easy to get close to the inner wall of the VTC, thereby reducin...
