Hello，I’m trying to do some deep learning quest on 3d reconstruction from lung x-rays (CT’s DRR). I want to take some features from DRR and use this to transform a initial template lung mesh to the ground-truth mesh, which needs a specific vertex number mesh model and a relation between the vertex and the DRR.
Here are my questions about data preparation:
- Can I get a specific vertex number surface model from a lung CT and its segmentation?(Now I can only export a surface model to STL or OBJ which has a random vertex number).
- I know that DRR is a synthetic x-ray for a CT. Can I get a DRR in slicer?
- If I get a DRR and the specific vertex number surface model, is there any way I can map the vertex of the model onto a DRR pixel?
- For the initial lung template mesh, can I get a mean shape mesh from different lung CTs?
Sorry for my stupid questions, I’m really poor in medical knowledge.
