Hi!
After the data was loaded into 3D Slicer,the axinal and coronal view display normally,but the saggital view was distored.
I cannot understand the reason about this problem,furthermore,whether it is possible the problem happened to axinal or
Sorry, I don’t know.The data of DICOM format was acquired through PACS (Picture archiving and communication system) and I have never met this problem before. So I consult with image doctor of our hospital, he have no idea about this too. The 3D Slicer is so powerful, so I think this problem could be solved with “reform” or “transform” module, but the result is failed.
@lassoan was able to share some sample data with me for testing so after a few tweaks yesterday the new code linked above appears to be working. It will be good for you to test it too with your data once we get it into a build of the application, which should be available in a day or two.
Thanks for the encouragement! Yes, I’ve been wanting to fix gantry tilted volume handling in Slicer for a long time too.
Since the the code is still new and relatively untested, @lassoan, @jcfr and I decided not to include it in the 4.8 release but will put it in the Nightly build after the release builds are made.
The pull request was merged today so it should show up in Nightly builds tomorrow. Would be good to know if it works for your data @doc-xie. Have a great weekend
Good job!Thanks you very much,Steve!
Would you like tell the the details about the steps?In other words,what should I do after I setup the new Nightly builds or is there any extentions should be downloaded?
Best wishes!

No special steps should be required, just importing into the DICOM module and then if there’s a gantry tilt detected the loaded volume will be put inside of a grid transform that straightens it out. Of course I’ve only tried this with a few datasets so let us know how it goes for you.
Ah, sorry, the solution I implemented only work with DICOM because that’s where the original image geometry information is available. I’m not sure there is a good solution for nii files unless you know the gantry tilt angle and can manually construct a shear matrix to correct it.
Thanks for your quick answer!
But where can I find the gantry tilt in the menu?Is it in the Metadata,and I shoul search it with word"tilt" ?
Best,
doc-xie!
