This newly published paper in the Journal of Applied Clinical Medical Physics by Dr. David Goodenough et al. details the physics behind the Wave module contained in the The Phantom Laboratory's Catphan® 700 phantom and automatically analyzed by the Image Owl Catphan QA service.

The Wave phantom can be used to sample the 3D resolution properties of a CT image, including in–plane (x,y) and z-axis information. The key development in this Wave Phantom is the incorporation of a z-axis aspect of a more traditional step (bar) resolution gauge phantom.
