Radial
k-space sampled data can be reconstructed using a variety of schemes such as
gridding, filtered back-projection (FBP), etc. Recently, the iterative
next-neighbor regridding (INNG) algorithm was proposed as a means for
accurate reconstruction. However, these algorithms have drawbacks in their
ability to reconstruct image from undersampled radial trajectory. Therefore,
we propose a new algorithm to reconstruct accurate images from undersampled
radial trajectory.
