Breath-hold or navigator-based MR acquisition has been widely used to remove the effect of motion from the images. However, breath holding can be challenging for patients. On the other hand, navigator-based methods suffer from lengthened acquisition time and the disturbance of magnetization history. In this respect, we will developed a self-gated free-breathing MR imaging method to obtain 4D MRI (3D spatial+1D respiratory phases) for deformable motion derivation.
