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.
