An IDEAL based Dixon reconstruction algorithm (Reeder et al. 2005; Yu et al. 2008). The method provides multi-peak fitting B0 field and T2- correction. The toolbox also provides a function for unwrapping phase data in 2D and 3D based on a best path method (Abdul-Rahman et al. 2007; Herraez et al. 2002). It also contains a function that allows simulating gradient echo Dixon data. Back››
