The invention relates to a noise reduction device for nuclear magnetic resonance examination. The noise reduction device effectively solves the problem that an existing noise reduction mode is poor innoise reduction effect. The noise reduction device comprises a bottom box, wherein a fixing block is arranged at the upper end of the bottom box, square frames are respectively arranged on the left side and the right side of the fixing block, the two square frames can move oppositely or back to back, a sliding sleeve is arranged in each square frame, the two sliding sleeves are symmetrical left and right, a noise reduction box is arranged on the sliding sleeve on the right side, and a sound insulation box and a plurality of sound absorption cotton layers are arranged in the noise reduction box; the thickness of the sound absorption cotton layers are sequentially increased from outer part to inner part, a power box is arranged in the sound insulation box, fan blades are coaxially and rotationally connected to the inner part of the power box, a sound production box is coaxially arranged at the left ends of the fan blades through a rotating shaft, a plurality of bells are arranged in thesound production box, sealing soft cushions are arranged on the noise reduction box, a telescopic box is arranged at the upper end of the bottom box, and two air bags are arranged in the telescopic box; and elastic balls are arranged at the lower ends of the air bags through connecting pipes and communicate with the power box on the corresponding side through air blowing pipes. The noise reduction device is novel in concept, ingenious in structure, convenient to operate and high in practicability.
Description
technical field [0001] The invention relates to the technical field of nuclear magnetic resonance auxiliary equipment, in particular to a noise reduction device for nuclear magnetic resonance examination. Background technique [0002] Magnetic resonance imaging, also known as spin imaging, also known as magnetic resonance imaging, is also called magnetic resonance imaging in Taiwan, China, and magnetic resonance imaging in Hong Kong, China. With different attenuation, the position and type of the atomic nuclei that make up the object can be known by adding the electromagnetic wave emitted by the gradient magnetic field detection, and the internal structure image of the object can be drawn accordingly. [0003] A lot of noise will be generated during MRI. This noise runs through the entire examination process, making the patient irritated, causing the body to shake, causing double images, resulting in inaccurate examination results, and prolonging the examination time. Prolo...
