Hi there, I’m trying to synthesize one full volume from multiple partial volumes(smaller FOV) of the same objects. I wonder if anyone else has explored this topic, and happy to hear any thoughts on what would be the best approach to this. I appreciate any ideas and advice on things to do or not to …

I updated the StitchVolumes module to respect soft-applied transforms in this PR: update to respect soft-applied transforms by mikebind · Pull Request #15 · PerkLab/SlicerSandbox · GitHub . Blending multiple overlapping image volumes where the overlaps could be in arbitrary directions is much more c…

Yes, you need to align the volumes in advance, but the module takes care of resampling and blending. If you find that some information is missing then please add the missing details (click the edit button in the github repository, make your changes, and when Github asks you then choose to create a p…

Great. So this is a fancy version of add volume, if I understand it correctly? I will document what I do and submit a pull request once I’m done.

The module does not add (compute sum of) voxel values of multiple volumes, but it stitches multiple volumes (by resampling, padding, cropping, and blending).

@lassoan is correct, the image volumes you want to stitch together must already be positioned where you want them in space. Then, you need an ROI which defines the region that the stitched volume should fill. I typically create this in two steps, go to “CropVolumes” module, select first volume t…

@lassoan @mikebind I just give stitch volumes a try. Unfortunately, I couldn’t find it when I did a module finder search after I installed the sandbox module.However, I can find the remove CT table module within sandbox. [Screenshot 2022-10-29 at 21.35.51] Platform; MacBook Pro OS: macOS Ventur…

Latest extensions are provided only for the latest Slicer Stable Release (currently 5.0.3) and latest Slicer Preview Release. You need to update from 5.0.2 to 5.0.3 to get this new module in the Sandbox extension.

@lassoan thanks. I just updated from 5.0.2 to 5.0.3. And it works. But all the previously installed extensions were gone. I wonder if Slicer3D supports update in a way that could still retain installed extensions

[image] Young_Wang: I wonder if Slicer3D supports update in a way that could still retain installed extensions Yes, this feature was added to Slicer-5.0.3 (you can bookmark favorite extensions and you can reinstall them by a single click).

Once again, thank you for all the help!

@lassoan @mikebind Apologies for keeping this issue open. I noticed some interesting behaviour of the stitch volume module, which could arise from my incorrect usage. I have some partial volumes of the same anatomy, the human ear, which I want to stitch together to construct a volume with a holisti…
