A respiratory motion correction method (SEGMO) is proposed for whole-heart coronary MRA. It eliminates the need for a diaphragm navigator, reduces imaging setup time, and has more accurate respiratory motion detection using an affine model. Its inherent 100% gating efficiency ensures a shorter and m

## Abstract In certain situations in magnetic resonance imaging the digital resolution in the frequency encode direction may be compromised by hardware limits on data digitization rates. We demonstrate a method of overcoming this restriction, without hardware modifications, by interleaving data fro

Time-series MRI data often suffers from image misalignment due to patient movement and respiratory and other physiologic motion during the acquisition process. It is necessary that this misalignment be corrected prior to any automated quantitative analysis. In this article a fast and automated techn
