Abstract
The techniques and systems described in this application can be used to, in one implementation, optimize data acquisition including sampling trajectories and undersampling factors. A method performed by a nuclear magnetic resonance imaging (MRI) system comprises applying a gradient and a radio frequency pulse sequence to an imaging target to partition a three-dimensional (3D) Cartesian k-space into a plurality of half projections in a ky-kz plane, the plurality of half projections divided into a plurality of interleaves, each interleave comprising one or more of the half projections and providing an asymmetric radial sampling of the ky-kz plane. Magnetic resonance signals are acquired to sample phase and slice encodings along each of the plurality of half projections. The magnetic resonance signal is processed to reconstruct at least one dynamic frame of the imaging subject to provide 3D volumetric imaging of contrast dynamics.
