Slab selective excitation combined with transverse read-out during continuous longitudinal table movement not only facilitates tumor staging and metastasis screening, the unlimited FOV will furthermore ease a variety of routine examinations on state of the art short bore scanners. A novel reconstruction method is presented which features compact implementation, high computational efficiency and is independent of k-space ordering. High-resolution 3D gradient echo data acquisition was performed during continuous table movement. The total acquisition time for a longitudinal FOV of 1800mm with a matrix of 192x119x900 and isotropic resolution was less than 5 minutes. The reconstruction method provided overall exact anatomical images.
