Abstract

Patient motion during data acquisition in magnetic resonance imaging causes artifacts in the reconstructed image, which for two-dimensional Fourier transform imaging techniques appear as blurring and ghost repetitions of the moving structures. In an earlier paper, Mitsa et al. proposed a technique for suppressing artifacts from periodic motion along the slice selection axis. In this paper a different approach to the same problem is presented which is not restricted to periodic motion. The algorithm is verified using a simulated phantom and motion. It is also shown to perform well in the presence of noise and motion within the imaging plane. © 1992 IEEE
