<p>A novel magnetic resonance imaging method is presented to produce a magnetic resonance image, wherein a stationary magnetic field and temporary magnetic gradient fields are applied. A sensitivity distribution (W(p)) maps the receiver sensitivity values of the receiver antennae system in an image domain. Transposition values (p(x)) map the positions in a spatial domain onto pixels (voxels) in the image domain on the basis of actual values of the stationary magnetic field and the temporary gradient fields. A folded image having aliased pixels (voxels) is then reconstructed from the magnetic resonance signals on the basis of a spatial encoding induced by the temporary magnetic field gradients. The aliased pixels (voxels) in the folded image are unfolded on the basis of the spatial receiver sensitivity map onto the respective signal distributions originating from different positions in the spatial domain so as to reconstruct the magnetic resonance image.</p> |
