Technical Field

The invention belongs to the fields of biology and new medicine, relates to the technical field of medical instruments, equipment and medical special software, and particularly relates to the technical field of novel pathological image recognition and analysis in the medical image diagnosis technology, in particular to an intelligent sound-insulation and noise-reduction system for magnetic resonance scanning, and also relates to a method for intelligently insulating sound and reducing noise by using the system.

Background

Magnetic Resonance, which is a common term in daily life, refers to Magnetic Resonance Imaging (MRI), which is a type of Imaging apparatus for medical examination made by using the phenomenon of nuclear Magnetic Resonance. Due to the structure of magnetic resonance, the magnetic resonance generates high-intensity noise when scanning a human body, and the diffusion of a noise source mainly has two diffusion paths, namely air propagation and solid contact diffusion. The noise is transmitted by the gradient coil through the two diffusion modes either directly to the ear of the patient to be examined or causes other parts to vibrate, a new noise source is generated and then transmitted to the ear of the patient. Currently, in magnetic resonance examinations, the patient may be surrounded by more than 110 dB of noise, which corresponds to a rock and roll concert | when being positioned in a single room! For the patient, suffering from the pain and uneasiness of the heart, coupled with the constant noise in the examination for as long as half an hour to an hour, undoubtedly increases the stress of the patient. Therefore, the patient feels uncomfortable symptoms such as dizziness and headache during the examination process, part of the patients are difficult to keep calm, and the coordination of the later examination is influenced, which directly influences the quality of the image. For doctors who need to face the magnetic resonance scanning every day, the doctors do not need to be exposed to high decibel noise for a long time while dealing with the ultrahigh strength work, the hearing of the doctors is easily damaged temporarily, a part of hearing is lost permanently after the doctors work for a long time, and the health status of the doctors is seriously damaged.

Furthermore, in principle, the noise of the magnetic resonance examination is unavoidable, but the noise can be controlled at different stages; the noise control can be realized by updating equipment, purchasing magnetic resonance equipment with a noise reduction function and preventing noise generation, and because the magnetic resonance equipment belongs to hospital standard, the magnetic resonance equipment with noise reduction function cannot be purchased again for replacement in a short time, so that the method is only suitable for newly-built hospitals, and the new noise reduction magnetic resonance equipment is higher in price and is not willing to be purchased by most hospitals; the noise can be prevented from entering the ear, the mode is generally carried out by wearing earplugs and the like, but the wearing of the earplugs and the like can completely isolate external sounds, the communication between doctors and patients is seriously affected, the magnetic resonance scanning time is easily increased, and the magnetic resonance imaging efficiency is greatly reduced.

In addition, the ferromagnetic material can not be close to the magnetic resonance chamber when the magnetic resonance examination is carried out, so that the dangerous condition is prevented, and therefore, when the noise of the magnetic resonance examination is subjected to noise reduction and sound insulation treatment, the ferromagnetic material product is avoided.
