Dataset

[Thermaloo]

Hi, thank you for your nice work! Could you provide part of the dataset to facilitate testing?

@lyqun Dataset can be share?

[lyqun]

Hi, we currently have no plans to make the data public since there are restrictions on the use of the data due to agreements with funding agencies. The preprocessing scripts are provided in ./data/knee_cbct/ and you can also run experiments on public CT datasets.

Hello, thank you for your beautiful work. When I used the public data set NSCLC to test the effect, I processed the data according to the steps you used to process the data and trained with the default parameters, but the contrast of the reconstructed image from the training result was very poor, which was far from the effect in the paper. Could you tell me where my problem was?

Thanks for your comments.

It seems that the method does not perform well on chest data. For your reference, we have conducted experiments on LUNA16, and PSNR/SSIM is 26.67/86.09 with 10 projection views.

Did you modify some parameters (e.g., channels, number of layers) of the model? This error means that the parameters of some layers are not matched with the loaded checkpoint.

No, I set it up exactly as in your paper. I re-tested it later. The training and testing are all the same checkpoint. However, with 24g of video memory, 10 views still cannot be accommodated, and only 4 views can be accommodated at most. In the case of 256256256 size
