Abstract

The invention relates to a noise reduction system used for reducing noise generated by a medical imaging device in a scanning room. The noise reduction system emits a noise reduction signal corresponding to a noise signal to a target region according to the detected noise signal in order to reduce or eliminate noise generated by the medical imaging device in the target region. The noise reductionsystem carries out noise reduction on noise in the target region in real time, i.e., carries out directional noise reduction on noise in the scanning room, noise reduction is targeted and easy to implement, the noise reduction effect is relatively good, and the personnel noise protection effect is relatively good.

Description

technical field [0001] The invention relates to the technical field of medical imaging equipment, in particular to a noise reduction system. Background technique [0002] During the use of medical imaging equipment, it will produce noise that makes patients feel uncomfortable. For some medical imaging equipment such as superconducting magnetic resonance systems, the noise generated by the switching of the gradient field is transmitted to the patient in the scanning channel through the air or the mechanical vibration of the components. This noise will not only cause discomfort and tension for the patient, but also affect the magnetic resonance. The quality of imaging may even cause permanent damage to human hearing. Therefore, the current medical imaging equipment is usually equipped with a noise reduction system. For example, by setting up sound insulation equipment in the medical imaging equipment, the noise transmitted from the medical imaging equipment to other areas is ...
