金属伪影Micro CT system is a recently developed imaging technique for small animal, which have very high spatial resolution and sensitivity, and is widely used in drug development, cancer detection et al. But in Micro CT, the artifact, specially the aliasing artifact, become serious as the ...
Purpose To mitigate a common artifact in spiral real‐time MRI, caused by aliasing of signal outside the desired FOV. This artifact frequently occurs in midsagittal speech real‐time MRI. Methods Simulations were performed to determine the likely origin of the artifact. Two methods to mitigate ...
utilizing a weighting function dependent upon parameters R and R, where radius R around an isocenter of the CT imaging system is selected in accordance with a low artifact criterion and Ris a parameter defining a transition region outside of radius R around the isocenter of the CT imaging ...
