Nuclear magnetic resonance detection system

Abstract

The invention discloses a nuclear magnetic resonance detection system. The nuclear magnetic resonance detection system is equipped with a nuclear magnetic scanning device and a sliding bed; a sound-proof cabin which is made of non-magnetic conductive materials is arranged on the sliding bed; a one-way sound transmission channel is arranged in the sound-proof cabin and communicates with the insideand the outside of the sound-proof cabin; and a sound transmission direction switching device is arranged in the channel. Noise which occurs during checking is isolated through the sound-proof cabin,so that embryos and pregnant women can be prevented from noise influence; and the pregnant women who stay in the sound-proof cabin can contact doctors through the one-way sound transmission channel.

Description

technical field [0001] The invention relates to the field of measurements for diagnostic purposes, in particular to nuclear magnetic resonance measurements. Background technique [0002] Every pregnant woman undergoes multiple ultrasound examinations during pregnancy to determine fetal growth. Ultrasound examination is a medical imaging diagnosis technology based on ultrasound. Its main principle is to make the ultrasound probe scan the uterus of pregnant women. During the scanning process, the ultrasound probe will continuously emit ultrasound and receive the reflected ultrasound after encountering the fetus. Determine the condition of the fetus. Although ultrasonography is routine, fetal images are blurry. Therefore, MRI is often used to examine the fetus when clear images of the fetus are required. [0003] The MRI machine will generate a lot of noise when it is working. The noise will not only affect the emotions of pregnant women, but also have a certain impact on th...

Problems solved by technology

[0004] Although the existing sound insulation device can play a certain sound insulation effect, the noise can still enter the sound insulation device along the unclosed position, therefore, the sound insulation effect of the existing sound insulation device is not good

Moreover, during the MRI examination, the doctor needs to communicate with the pregnant woman from time to time to guide the pregnant woman to perform the examination in the correct way. Therefore, the pregnant woman needs to repeatedly take the earplugs, which will also have a huge impact on the mood of the pregnant woman.
