Patent ID: 7945305

Claim:
A method for acquiring and producing images of a time-varying subject with a magnetic resonance imaging (MRI) system, the steps comprising: a) performing a prescan of the time-varying subject that includes: a)i) estimating a dynamic model for the time-varying subject; a)ii computing a dynamic sampling schedule using the estimated dynamic model, the sampling schedule including information indicative of locations in k-space, and an order and timing in which the locations in k-space are to be sampled; and a)iii selecting a pulse sequence for directing the MRI system to acquire k-space image data from the time-varying subject; b) performing a scan of the time-varying subject to acquire k-space image data with the MRI system that includes: b)i acquiring information indicative of the motion of the subject caused by respiration; b)ii altering during the scan one of the information in the dynamic sampling schedule indicative of the locations in k-space, the order in which the locations in k-space are sampled, and the timing in which the locations in k-space are sampled, or the selected pulse sequence to compensate for respiratory motion of the subject; and b)iii acquiring k-space image data with the MRI system using the sampling schedule and the selected pulse sequence; and c) reconstructing an image using k-space image data acquired in step b).
