Abstract

A method for acquiring an image volume using a magnetic resonance imaging device includes performing an acquisition process to acquire a first dataset corresponding to a first portion of an anatomical region of interest at a first slice resolution, wherein the first dataset comprises a first plurality of three-dimensional slabs or a first plurality of two-dimensional slice regions. Additionally, one or more additional acquisition processes is performed to acquire a second dataset corresponding to a second portion of the anatomical region of interest at a second slice resolution that is lower or higher than the first slice resolution, wherein the second dataset comprises a second plurality of three-dimensional slabs or a second plurality of two-dimensional slice regions. Once the datasets are acquired, a reconstruction process is applied to jointly reconstruct the first dataset and the second dataset as a single consistent volume.
