Project Title - MATLAB image processing tutorial

This page accompanies a MATLAB tutorial which simulates some artifacts that might be found in MR images. Their causes, and in some cases corrections, are demonstrated in the code. One- and two-dimensional examples are provided.
Image artifacts in this tutorial include DC Offset, Quadrature Ghosting, RF Noise, Gradient, and Frequency-Sampling Jitter. Information on the first four topics can be found in Hornak, Joseph P. The Basics of MRI, Chapter 11. More information on the mathematical derivations can be found in Smith, Julius O. Mathematics of the Discrete Fourier Transform (DFT).
