Deep learning corrects artifacts in RASER MRI profiles.

A newly developed magnetic resonance imaging (MRI) approach is based on "Radiowave amplification by the stimulated emission of radiation" (RASER). RASER MRI potentially allows for higher resolution, is inherently background-free, and does not require radio-frequency excitation. However, RASER MRI can be "nearly unusable" as heavy distortions from nonlinear effects can occur.
