About block coordinate

Excellent job! I am using your method to combine DRR images of vertebrae for CT reconstruction. However, I have some doubts about the generation process of blcoks in the dataset. I couldn't find detailed explanations in the paper. Can you explain how blocks are generated? Looking forward to your reply. Thank U!

Blocks are generated for faster data loading. Instead of saving all volumes in one file, we split them into many blocks (64^3) and randomly load one of them at each training iteration. It is ok to not use the blocks, but the loading speed will be slower.
