Hello, I just need to detect metal artifacts not reconstruct. Could you recommend any papers or resources where I could get an idea of this? In addition to metal artifacts, I have other artifacts on my data, such as aliasing and streaking. I tried using Shannon entropy and Fourier transform and used it directly on the voxel data (I just did skull stripping as pre-processing so it doesn’t include the streaking on bone) but didn’t get the stable threshold to separate the good CT scans and the artifacts’ scan.  
I would really appreciate your help.
