Why Was This Recalled?

Issue with the algorithm for ROI contraction in RayStation 4.7 when non-uniform contraction distances are used. The ROI contraction tool uses six distances as input: right/left, inferior/superior and posterior/anterior. These contraction distances are, in error, pairwise reversed, i.e. right is interpreted as left, inferior is interpreted as superior, and posterior is interpreted as anterior.
