A new propeller EPI design using short axis readouts
Skare S, Newbould R, Bammer R, Clayton D
A new propeller EPI design is presented. Difference to earlier propeller EPI method is that the readout is played out along the short-axis rather than the long-axis of the blades. This results in reduction of Nyquist ghosts and distortions per blade, which means less blurring in the reconstructed image. Also, since the number of phase encoding points of the blads determines k_max, higher image resolutions does not increase the distortions and blurring.
