I tested your "d32_laminography.py" which works well, but when I change the lami_angle from 10 to 40, then the reconstructed image is too bad. Could you explain why that happens?...

Now I can see better a slice image after change the size of detector by 512. As you can see the geometry figure, the detector is parallel to Z-axis, which...

Thanks for your nice guidance. Now I can see the tilted geometry of CBCT and some slices too with SART algorithm.

I guess that your right_side offscan mechanism has some issue. I tested your "d23_offscan.py" which shows some strange reconed slice and like attached one. I just change the +100 offset...

I have checked your v1.11 version about the offscan issue. And I could see that there is still a FOV limit issue at the case of left-side offscan with the...

I have checked the version 1.12 which included in charmley-dev branch, and I can see the FOV-limit issue of off-scan has been cleared now. My GPU is RTX-3090TI with 24GB...

@kylechampley. I found the almost same issue which named as "ramp-filter missing issue" by me. As you can see below image, after doFBP, the recon slice shows very blurred one...

 

I found the key function for making this blurry result, that is the custom volume setting function which is 'leapct.set_volume()'. If I use leapct.set_default_volume() function, then there is no such...

I think that this method costs too much resource and time for real usage. As you know it needs three more recons both single and iterative ones.
