Noise-maskable head rest structure for magnetic resonance inspection

Abstract

The invention discloses a noise-maskable head rest structure for magnetic resonance inspection. The noise-maskable head rest structure comprises two inspection benches which are arranged in parallel,wherein bench plates and supporting plates are fixedly welded to the upper and lower parts of inner sides of the two inspection benches separately, slideable moving rails are separately arranged at the two sides of the tops of the bench plates, foldable arc-shaped frames are arranged at tops of the moving rails, and ear covers are arranged on bevel faces of the arc-shaped frames. According to thenoise-maskable head rest structure, the two arc-shaped frames can be adjusted to an optimum position according to the width of a head of a patient, and then, ears of the patient can be subjected to soundproofing treatment by using the ear covers and extend into recesses of the ear covers, so that the soundproofing effect is better, an earplug type sound arrester is replaced, the wearing of an inspected person can be more comfortable, the operation is simple, the use is convenient, the degree of comfort of a magnetic resonance inspection process is increased in case of good soundproofing effect, and the normal proceeding of magnetic resonance inspection of special people is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical equipment and devices, in particular to a noise-shielding headrest structure for magnetic resonance examination. Background technique [0002] Magnetic resonance refers to the phenomenon of spin magnetic resonance. Under the action of an external magnetic field, Zeeman splits the spin energy level, and the physical process of resonantly absorbing radio frequency radiation of a certain frequency. Nuclear magnetic resonance spectroscopy is a branch of spectroscopy. The resonance frequency In the radio frequency band, the corresponding transition is the transition of nuclear spin on the nuclear Zeeman energy level. In medicine, it is a kind of imaging equipment for medical examination made by using the phenomenon of nuclear magnetic resonance. It has become a common imaging examination. As a new type of image examination technology, nuclear magnetic resonance imaging will not affect human health, but...

Problems solved by technology

[0003] In the process of MRI examination in the hospital, the MRI equipment will produce a certain amount of noise, and the noise generated is relatively loud. Therefore, it is difficult to ensure the normal progress of the examination when examining young children or patients with heart disease, which may affect the physical and mental health of young children. Therefore, it is necessary to carry out sound insulation treatment for such special groups of people. The existing sound insulation devices are much larger and use earplugs. This method has limited sound insulation effect and poor effect
