Suppression of MRI Truncation Artifacts Using Total Variation Constrained Data Extrapolation

<table>(Top) One-dimensional profile of a rectangle
reconstructed by Fourier transformation from 96 Fourier samples (solid line) in
comparison to the true function (dotted). While the true function is piecewise
constant, the Fourier reconstruction exhibits severe ringing artifacts due to
truncation of the Fourier coefficients, which causes an increased total
variation (TV) value. (Bottom) Magnified view.</table>
