Parallel Imaging of the Prostate at 7T using a B0 Crusher Coil to suppress Aliasing Artifacts

A many element body receive array has a high, but inhomogeneous receive sensitivity. When performing parallel imaging of the prostate at 7T, aliasing artifacts occur due to this inhomogeneity. A B0 crusher coil, which is placed around the patients waist, can suppress these artifacts by crushing the signal coming from the outer rim of the patient while the signal coming from the prostate stays unimpaired. Compared to other methods, this technique can be used in combination with each desired sequence.
