| Issue: | The issue occurs if one or more treatment plans with at least 2 isocenters based on one planning CT are used, and when a cone beam CT has been acquired for each isocenter. The system supports the workflow correctly until the user performs a manual change to another isocenter. At this point the visualization of the overlying images in Adaptive Targeting might be incorrect. If in this case the user performs a manual registration of the overlying images, this may result in an incorrectly calculated offset in Adaptive Targeting. Applying this offset to the actual patient position can lead to delivering dose to the wrong location and therefore to patient mistreatment. |
