Magnetic resonance imaging (MRI) is a state-of-the-art medical imaging technique that can determine the structural and functional status of body tissues and organs. However, the prolonged MRI acquisition time increases the scanning cost and limits its use in emergency settings. Moreover, subjects have to lie still in the scanners and even hold their breath for thoracic or abdominal imaging. Hence, the slow acquisition of magnetic resonance (MR) images presents significant inconvenience to patients and healthcare systems alike.

扫描问题

磁共振成像（MRI）是一种最先进的医学成像技术，可以确定身体组织和器官的结构和功能状态。然而，延长的 MRI 采集时间增加了扫描成本并限制了其在紧急情况下的使用。此外，受试者必须静止地躺在扫描仪中，甚至屏住呼吸进行胸部或腹部成像。因此，磁共振 (MR) 图像的缓慢采集给患者和医疗保健系统等带来了极大的不便。
