Abstract
Exemplary probes including longitudinal marker elements arranged parallel to the probe axis are provided for reducing or eliminating non-uniform rotational distortions (NURD) in imaging systems. Additional ring marker elements may also be provided to reduce or eliminate non-uniform linear distortion (NULD). These probes, as well as systems and methods of use provide for images having better image quality and reduced NURD.
