Curved planar reformation

摘要

Curved Planar Reformation (CPR), producing a Curved Planar Reformat, is a technique to provide a representation of an anatomical structure which is curved through a 3D volume. This reformation process can result in image artifacts, leaving it up to the user to determine what are artifacts and what are actual anatomical features. The invention provides assistance to the user by detecting areas of potential ambiguity during the CPR procedure, and distinguishing these areas on the display to the user. In this way, the user no longer needs detailed knowledge of how the CPR is performed.

主权项

1. A system for displaying a curved planar reformation plane, comprising:
an imager configured to provide imaging data of an anatomical structure; a determiner configured to determine a line through the anatomical structure; a curved planar reformatter configured to:
determine the curved planar reformation plane at a plurality of positions along the line; anddetermine for one or more voxels in the imaging data a likelihood that the voxel(s) will be comprised in more than one location of the reformation plane; a display configured to display a representation of the anatomical structure in the reformation plane, and further configured to distinguish the one or more voxels if the likelihood deviates from a predetermined value or range of values.
