Off-resonance correction reconstruction, which was determined with two gradient echo images with echo time difference Δ TE=0.5 ms. Above: complete map. Below: section around the aorta. Middle: Uncorrected magnitude image of the radial measurement. Around the aorta severe blurring artifacts are visible. Right: Using the measured off-resonance map and the previously mentioned algorithm the radial images can be de-blurred.
