Help needed in removing the shifts in the reconstructed slices (##HELP WANTED)

12

Hi I tried reconstruction using the FBP algorithm. The objects in the reconstructed images were observed to be shifted in a vertical direction. The images were taken with a static...

How to specify image dimensions for reconstructed images

6

Hello, I run `SART` algorithm for reconstructing images. I understand that the function `dataPreprocess` resizes the projection data to contain only the needed object and `SART` algorithm reconstructs images to...

CUDA based projection and backprojection calls in SART

6

Hello, I compiled the `.sln` files under` Functions/Sources` in `Visual studio IDE` and built files `backprojectionDDb_mex_CUDA.mexw64` and `projectionDDb_mex_CUDA.mexw64`. SART algorithm requires projection and backprojection to run for each iteration and...
