How to merge two CT series (Thorax + AbdoPelvis) into one continuous volume in Slicer 5.10

Support

Hello everyone,

I’m working on a quantitative imaging project and I have two CT series from the same patient:

  • one Thorax series (Thorax MEDIASTIN 2.0 MPR ax)

  • one AbdoPelvis series (PORTAL 2.0 MPR ax).

Both are from the same acquisition session, with similar spacing (≈ 2 mm) and kernel, but they are stored as two separate series in DICOM.
I would like to merge them into one single continuous volume (thoraco-abdominopelvic) for segmentation and radiomic analysis.

Question:
What is the correct way (either via GUI or Python) to merge two contiguous CT volumes into a single continuous one in Slicer 5.10, preserving HU values and patient coordinates?
Is there a recommended extension or function for this (e.g., Merge Volumes, SlicerMorph, etc.)?

Any example code or workflow would be greatly appreciated.

Thanks a lot for your help!
Julien
