ABSTRACT
Magnetic Resonance Imaging (MRI) has become a major non invasive imaging modality over the past 25 years, due to its ability to provide structural details of human body, like Computed Tomography, and additional information on physiological status and pathologies, like nuclear medicine. The reconstruction of a single MR image usually involves collecting a series of trajectories. The measurement of a trajectory is a sampling process of a function evolving with time in a 2D or 3D space domain, referred to as “k-space”. The raw data from this sequence of acquisitions are then used to reconstruct an image, through Fourier Transform after gridding (O’Sullivan 1985, Jackson et al. 1991).
