Abstract
A magnetic resonance image of a subject is generated by acquiring k-space samples by sampling an elliptical central area of k-space, k-space having a plurality of points. Each point is representative of a potential sample. An elliptical peripheral area of k-space which peripheral area surrounds the central area is partially sampled. Respiratory motion of the subject is detected and the magnetic resonance image of the subject is reconstructed using the k-space samples acquired before the detection of respiratory motion.
