RECONSTRUCTION OF A MAGNETIC RESONANCE IMAGE IN IMAGE SPACE USING BASIS FUNCTIONS (RIB) FOR PARTIALLY PARALLEL IMAGING

摘要

The invention pertains to parallel Magnetic Resonance Imaging (MRI) and provides a method for image reconstruction in image space. The method can suppress aliasing caused by undersampling when the number of sampling lines in k-space is reduced to increase the imaging speed. In the reconstruction, the sum of square errors can be minimized within a region of interest, which can allow the image reconstruction to be optimized in a particular imaging region of interest by sacrificing the reconstruction of other regions. Image reconstruction can be implemented region by region, allowing global optimization by spending a longer time in reconstruction.
