Thanks, I will try to investigate.
Admitedly, I have myself never tried DBT data and everything in TIGRE has been validated by third party users of TIGRE, so I am not entirely sure if all is correct. DBT is a tough one, as due to the very limited angular sampling that you have, the results you show may be correct, as limited angle artifacts are almost unavoidable. Do you have a compercial DBT recon to compare against?
Have you checked if the angles are negative? its a very common issue
@AnderBiguri Thanks for your response. Do you mean the geo.offDetector which angle is negative? I don't have a commercial DBT, so I can't compare it.
I will try to check the angle issue to see whether improve the image quality or not. Thank you!
Hi @JingYao0512 , I meant angles=-angles;
. A really really common error is giving TIGRE the angles in the opposite direction. in DBT its really hard to know if there is such mistake by looking at the image, as the images tend to look bad anyway. So double and triple check the geometry!
Closing from lack of response, but feel free to open again if you have issues.
