Hi 3d slicer experts
I am working with some modules in slicer RT extension ; and I have radiation fields and some organs such as heart and lungs. I want to calculate the the geometric volume of heart (mm3) wich is located in the radiation field . Is there a module or another software wich calculates this geometric volume for me?
thanks a lot
You can segment the heart using Segment Editor module and compute its volume using Segment statistics module.

Hi 3D slicer experts
Thanks for your response. My images have already been contoured by an oncologist . In some slices a part of the heart lies in the radiation fields (red area in following figure) . The sum of these slices is the volume of the heart located in the radiation fields and I just want to calculate the geometric volume of these areas(red areas in multiple slices).
1-wich module should I use?
2- If there is a need to re-segment for the the red areas, is there any possibility of automatic segmentation?
thanks a lot
@cpinter Can we import beam models into segmentation node?
Yes, you can import beam models as any other models to segmentations in the Segmentations module, copy the beam segment into the segmentation that contains the heart. Then use Segment Editor’s Logical operator effect to get their intersection, then the Segment statistics module to calculate volume etc.
