Rotating blade trajectories, such as RUKSE and PROPELLER have been proposed as improvements for a variety of applications. For these non-Cartesian trajectories, modulation in the gridded K-space can arise at the overlap between blades, which would ideally be addressed by the Density Compensation Function. This work proposes two alternatives to the Jackson method for blade imaging and confirms for TrueFISP Blade Imaging in the Steady State (TrueBLISS) that Amateur Hack is a rapid alternative to the Jackson method, but Iterative Grid / De-Grid yields superior results.
