Description

Technical Field

[0001] The invention relates to the technical field of protection devices, and in particular to a nuclear magnetic resonance abdomen coil protection device. Background Art

[0002] When performing magnetic resonance imaging in clinical practice, operators often place the coils needed on the patient's examination site. This coil is what we often call a surface coil. When performing abdominal examinations on patients, flexible coils are used. This allows the subject to be as close to the coil as possible to increase signal strength and thus achieve the purpose of improving image quality. However, in the current use of abdominal coils, they are usually fixed with Velcro. Not only will the fixation effect of Velcro deteriorate after long-term use, but after fixation, the patient cannot adjust the body posture according to the needs of the test and needs help from others to readjust the fixation. Secondly, when the patient adjusts the body position, it may cause wrinkles or local deformation of the abdominal coil, resulting in damage to the internal electronic components. Summary of the invention
