A key challenge of MRI is development of an accurate model of noise generation which are integral to generation of high-resolution images. Currently, motion induced noise is addressed at algorithmic level. Here, we present a novel physical model which incorporates the role of mechanical vibration of body parts in generation of additional frequency components in the emitted radio frequency spectrum around the precession frequency. The mathematical model was validated through a computational simulation which led to the discovery that beats generated as a result of mechanical vibrations of the source lead to ghosting and blurring effects.
