In rare cases, the SSD (source to skin or surface distance) calculation algorithm will miss the entry point of the ROI and instead calculate the distance to the exit point, resulting in an incorrect SSD. The SSD will be incorrect in UI, Dicom export, plan report, and scripting. If the bug is triggered when an intended SSD is entered in Raystation, the intended SSD will be displayed and exported, but the actual SSD of the plan is shorter than intended.
