Description

Technical Field

[0001] This utility model relates to the field of medical device auxiliary technology, and in particular to a special pad for prone examination of the spine using magnetic resonance imaging. Background Technology

[0002] Magnetic resonance imaging (MRI), due to its excellent soft tissue contrast and lack of ionizing radiation, is widely used in imaging the human spine. In clinical radiology examinations, the diagnosis of certain diseases, such as tethered cord syndrome and lumbar disc herniation, sometimes requires a prone MRI in addition to the routine supine MRI for definitive diagnosis. However, during a prone MRI, the patient's normal breathing causes chest and abdominal movements, resulting in up-and-down movements that create artifacts on the MRI image. Furthermore, the patient's head-down position can lead to breathing difficulties, further exacerbating respiratory movements and worsening image artifacts.

[0003] Therefore, a special mat for prone MRI examination of the spine is proposed. Utility Model Content
