Hello I would like to induce some deformation and changes in an PET/CT image preferably programmatically for example elastically deform aorta , add some gas bubbles, change size of the inflammatory infiltration … I want to use it for some data augmentation.
How best to approach this (for example what library to use, better in C+ or python - as far as i know there is/was limitad capability to load external libraries in python, some extension … ?)
Thank You for help !
Some of that can already be done with TorchIO, and maybe you can expand it to add some extra features.
Thank you! Yes I would like to contribute in case you would have some clues where to start, you can let me know 
Thanks, Steve.
@Jakub_Mitura, I suggest you use Python for data augmentation. As @pieper said, TorchIO can be used for e.g. random elastic deformations. The transforms you’re after are quite level and problem-specific, so they would require some work. You can start by checking the tutorials that demonstrate how to use some of the transforms during training.
You can use Slicer to visualize your results or try the transforms parameters. If you have more questions that unrelated to Slicer, you can open a discussion in the TorchIO repository.
Ok thanks ! So i will dive into it slowly and when I will achieve sth i will share the results with you, in case i will get stuck i will post as you suggested, thanks!
