Description

Technical Field

[0001] This utility model relates to the field of medical devices, and more specifically, to a magnetic resonance imaging (MRI) examination bed. Background Technology

[0002] An MRI scanner is a device used for magnetic resonance imaging (MRI) examinations. This device uses magnetic fields and radio waves to generate detailed images of the inside of the human body, which can be used to diagnose and monitor a variety of diseases and lesions. An MRI scanner typically consists of a large magnet, radio transmitting and receiving coils, and a bed that supports and positions the patient. During an MRI examination, the patient lies on the bed, which moves within the magnetic field to center the area to be examined. The system then generates detailed images by sending radio waves into the patient's body and detecting their reflections. MRI examinations are commonly used to diagnose diseases and injuries in areas such as the brain, spine, joints, abdomen, and pelvis. Children's fear, hyperactivity, and the noise of the machine can cause them to move around a lot, making it difficult to scan successfully. Therefore, it is necessary to effectively restrict their bodies to ensure the accuracy of the scan data. Therefore, a magnetic resonance imaging (MRI) examination bed is proposed to address the above problems. Utility Model Content
