We propose a method for fast MRI needle tracking using Compressed Sensing, view-sharing and co-RASOR reconstruction of a 2D radial UTE acquisition. The method reconstructs positive contrast at the location of the needle at a high temporal resolution, as well an anatomical background image at a lower temporal resolution, but with increased spatial resolution. Results in a phantom show good needle contrast at 4x acceleration, resulting in about 4 frames per second for the needle image and about 1 frame per second for the background image.
