摘　　要：如何增强成像对比度是磁共振成像领域的研究热点之一,辐射阻尼(RD)对样品微小差异有较强的敏感性,通过正反馈增强辐射阻尼可提供全新的对比度机理。通过建立正反馈增强模拟算法,模拟分析了不同参数下的对比度机理,并结合新的磁共振方法(iMQC),探究了共同作用下的磁共振成像特性。这将有助于探索辐射阻尼在磁共振成像领域的应用。Enhancing imaging contrast is one of the research issues in the field of magnetic resonance imaging （MRI）. Radiation damping （RD） is more sensitive to small differences among samples. A new imaging contrast principle is provided through regenerative feedback enhancement radiation damping. By establishing regenerative feedback enhancement simulation algorithm, the imaging contrast principle is simulated and analyzed at the condition of different parameters. Incorporating with a new magnetic resonance image method （iMQC）, MRI characteristics under synactic effect are discussed. It is helpful to explore the applications of radiation damping in the area of MRI.
