This work presents a new, center-out, rapid 3D trajectory based on spirals. It has very uniform sampling density, and good suppression of aliasing and motion artifacts. A unique feature is that, with little penalty in time, it samples most of k-space twice, in orthogonal directions, making it a good method undersampling for parallel imaging or compressed sensing.
