DVH Estimation output error

Jan 5 at 4:31 PM
I am working on automated scripting using various DVH Estimation Models (i.e. rapidplan).

I am getting the error: "ERROR: Could not create calculation data object. Image does not define CT scanner."

I am sure this is happening during the function call to CalculateDVHEstimates().

This is a confusing error and I cannot help but think it is due to some setup issue with my system rather than a RapidPlan model error.

Can anyone provide any guidance and/or assistance with this? Thanks.

Scratch this post....

The issue was the original database setup on the research machine. The system was imported over to the new machine, but the CT scanner was not 'attached' to the plan (even though it was listed in RT Administration setup).

I tried to MANUALLY optimize my plan and a dialog box popped up asking if I wanted to attach the CT scanner to this plan.

After this, the error disappeared and I was able to extract the DVH estimates.

Keep on searching .... the answer will appear....
