Systems, methods, apparatus, and other embodiments associated with reducing imaging acquisition time are described. One example method includes accessing an under-sampled data set and a library of previously acquired data sets. The method includes producing an approximation of the under-sampled data set by transforming data stored in the library. The method includes producing a sparsified data set from the approximation and the under-sampled data set and then reconstructing the sparsified data set into a sparse image using a reconstruction technique configured to reconstruct sparse data. The method includes producing a fully-sampled approximation of the under-sampled data set and producing a final reconstructed image from the sparse image and the fully sampled approximation.

Reducing acquisition time

Example systems, apparatus, circuits, and so on described herein concern intervention-independent scan plane control for an MRI system. A tracking device capable of being manipulated independently of an interventional device in use to treat a patient transmits position signals describing an orientation of the tracking device to an MRI system. The MRI system determines a desired scan plan that will correspond to the orientation of the tracking device and performs a diagnostic scan on the desired scan plan.

Example systems, methods, and apparatus concern non-Cartesian CAIPIRINHA (Controlled Aliasing In Parallel Imaging Results IN Higher Acceleration). One example parallel magnetic resonance imaging (pMRI) apparatus includes a radio frequency (RF) manipulation logic configured to control the pMRI apparatus to perform a non-Cartesian CAIPIRINHA acquisition process in which under-sampled data is acquired using a non-Cartesian (e.g., radial) pattern. The apparatus also includes a reconstruction logic configured to reconstruct the under-sampled data as a function of phase shift applied by the non-Cartesian CAIPIRINHA acquisition process and coil sensitivities acquired during the non-Cartesian CAIPIRINHA acquisition process.
