Method and apparatus for view ordering of magnetic resonance imaging data for dynamic studies

摘要

A method for acquiring magnetic resonance (MR) data for a three-dimensional (3D) dynamic study includes partitioning a k_y-k_z plane with a plurality of views into an inner region and a plurality of outer regions. The inner region includes a set of views in a central region of the k_y-k_z plane and each outer region includes a plurality of views outside of the central region of the k_y-k_z plane. The method also includes partitioning each outer region into a plurality of radial fan beam segments, defining a first view ordering for the inner region and defining a second view ordering for each outer region. Once the k_y-k_z plane is partitioned and the view orderings are defined, MR data is acquired for the set of views in the inner region and for all of the views in each of the outer regions in an alternating acquisition order where the set of views in the inner region are acquired more frequently than the views in each of the outer regions. At least one MR image is generated based on the acquired MR data.
