Abstract:
1. A method for self-gating an imaging study with a magnetic resonance imaging (MRI) system, the steps comprising: a) acquiring, with the MRI system, a k-space data set from each radio frequency (RF) receiver coil in a coil array, each acquired k-space data set including signal variations indicative of motion of a portion of a subject that occurs relative to the respective receiver coil; b) selecting a portion of the k-space data sets acquired in step a) as reference data; c) comparing the acquired k-space data sets with the selected reference data in order to produce a gating signal indicative of the motion of the portion of the subject that occurred relative to the coil array; and d) utilizing the produced gating signal to reconstruct an image of the subject from the acquired k-space data sets in which motion of the portion of the subject is substantially suppressed.
