Magnetic Resonance Imaging (MRI) & Prospective Motion Correction in MRI
 
	In the last twenty years MRI has developed to a widely used medical imaging technique.
The possibility to provide hundreds of different contrasts between soft tissues
in extremely high resolution is essential for an optimal diagnosis and has made MRI
indispensable in clinical routine. However, long acquisition times make the technique
extremely vulnerable to motion and examination of patients unable to cooperate has
been problematic since the early days of MR.
	Prospective motion correction with external position tracking has the ability to
provide a general approach to this problem. As tracking information is acquired
simultaneously to the MR exam, the sequence can be adapted to position changes
in real-time. In theory all spatially encoded MR sequences might benefit from
such real-time adaption without the penalties like scan prolongation or additional
discomfort for the patient.
