ABSTRACT:
A method for collecting data representative of a magnetic resonance image includes two or more data collection cycles in which different gradient fields are applied. A first data set collected in the first cycle leaves a portion of k-space inaccessible because of dead-time in the MRI machine. The second data set, collected in the presence of a different gradient, reaches back to populate a portion of the previously inaccessible portion of k-space.
