I think my question is quite a beginner question, but since a year now I am doing freehand 3D ultrasound and I just realised that the ROI I am using has a lot of impact on my volume reconstruction.
I am therefore trying to adjust the ROI the more possible to the axis of my sweeps.
However I cannot find how to rotate the ROI ? I tried applying a transform to the ROI, but then the volume reconstruction did not work anymore …
Currently in the Volume Reconstructor module in Slicer you cannot specify axis directions. I’ve submitted an issue to make sure it gets implemented:
Would you like to give it a try and implement it. We can help you getting started, but it requires basic C++ programming skills.
Alternatively, you can rotate your entire reference coordinate system by applying adding a custom transformation. For example, you can add ReferenceToRotatedReference) and send all transforms and images in RotatedReference instead of Reference.
Thank you for your quick answer.
I apologize but I do not think I have the skills to implement this in Slicer …
As you offered, I applied a custom transformation to my full trial and the volume reconstruction worked well !
However, my ROI and the axis of my sweeps change for each acquisition I do, since I am sweeping different muscles of different sizes in different body positions … . so it would be a lot easier for me if it was possible to directly adjust the ROI size and orientation.
How can I be kept updated if that becomes possible someday?
Thanks again,
Cheers,
Aurélie
Dear Andras,
I see that this issue has been resolved on the 21st of November 2021.
Has it been developped only on PlusServer (as a code line) or also directly in the 3D Slicer GUI ?
Thanks in advance for your help.
Best regards,
Aurélie Sarcher
