On the Empirical Effect of Gaussian Noise in Under-sampled MRI Reconstruction

3 Oct 2016Patrick VirtueMichael Lustig

In Fourier-based medical imaging, sampling below the Nyquist rate results in an underdetermined system, in which linear reconstructions will exhibit artifacts. Another consequence of under-sampling is lower signal to noise ratio (SNR) due to fewer acquired measurements... (read more)
