AI Technical Summary
In current MRI scans, children, elderly patients, and patients with Parkinson's disease find it difficult to remain still for extended periods, leading to involuntary movements that affect image clarity and diagnostic accuracy. Furthermore, traditional fixation methods are not user-friendly for parents of infants and young children, as they may require general anesthesia, increasing medical costs and risks.
A human fixation frame for MRI was designed, including a base plate and side panels, and is equipped with slides, strap holes and a position locking mechanism. It uses materials permitted by MRI and achieves flexible fixation of the patient's limbs or head through the cooperation of sliders, guide rods and flexible straps.
It effectively reduces image blurring and fuzziness caused by involuntary movements, improves imaging clarity, reduces the need for general anesthesia, and lowers medical risks and costs. At the same time, the material selection does not interfere with the magnetic resonance imaging equipment, ensuring safety and stability.
