In the generalized theory of SENSE imaging the reconstruction matrix is defined by choosing a set of desired voxel functions. Either in the strong voxel approach (SVA) the resulting voxel functions are generated by a least squares minimization or in the weak voxel approach (WVA) by constraining the orthonormality relation to the desired voxel functions. In this work, the reconstruction accuracy of the SVA and WVA of SENSE imaging depending on the choice of the desired voxel functions is evaluated.
