Why Was This Recalled?

This notice concerns a problem with the computation of ROI voxel volumes for cases where the CT has variable slice spacing. The dose grid volumetric representation of an ROI can be wrong. This affects all dose-volume properties for such ROIs, including DVH, dose statistics, clinical goals and constraints or objective functions. Furthermore, if material override ROIs are used, or if the external is not represented by contours, the bug can trigger an error in the 3D dose distribution.
