Abstract:
3D printing in MRI-compatible plastic resin has been used to fabricate and implement a geometric distortion phantom for MRI and CT imaging. The sparse grid structure provides a rigid and accurate phantom with identifiable intersections that are larger than the supporting members, which produces images that are amenable to fully automated quantitative analysis using morphometric erosion, greyscale segmentation and centroiding. This approach produces a 3D vector map of geometric distortion that is useful in clinical applications where geometric accuracy is important, either in routine quality assurance or as a component of distortion correction utilities.

Claim (Index 2):
The method according to  claim 1 , wherein the location of the control points in the image is obtained by segmenting the boundary of the 3D image of the phantom using at least grey-scale threshold values, and subsequently performing morphological erosion of the boundary by removing a specified number of boundary surface elements
