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.
