MOET is a 2D sampling scheme based on radial sampling combined with oscillating gradients providing incoherent aliasing artifacts. This is essential to the success of Compressed Sensing algorithms. Real-time in-vivo cardiac data along a MOET and a standard radial trajectory were acquired and reconstructed using CS exploiting sparsity in the frequency domain with a temporal resolution of 51.2ms per frame. The reconstructed MOET images exhibit an overall improved image quality with fewer residual aliasing artifacts compared to the radial trajectory.
