Abstract:
1. A method for acquiring and producing images of a time-varying subject with a magnetic resonance imaging (MRI) system equipped with parallel imaging hardware, the steps comprising: a) performing a prescan of the time-varying subject that includes: a)i estimating coil characteristics for a plurality of receiver coils in the parallel imaging hardware; a)ii estimating a dynamic model for the time-varying subject; a)iii computing a dynamic sampling schedule using the estimated dynamic model and coil characteristics, the sampling schedule including information indicative of the position in k-space, order and timing at which k-space image data is to be acquired; and b) performing a scan of the time-varying subject using a pulse sequence that directs the MRI system to acquire k-space image data through the plurality of receiver coils using the dynamic sampling schedule; and c) reconstructing an image using the k-space image data acquired in step b).
