7 Common Problems with X-ray CT & How To Avoid Them
- Resolution is too low
- Can't scan the whole sample
- CT image is all too dark or too bright
- There is no density contrast
- Scans take too long
- Files are too big
- Analysis is too involved
1. Resolution is too low
2. Can't scan the whole sample
There are three possible reasons why you can't scan the whole sample.
- The sample doesn't fit into the CT scanner.
- The sample is larger than the largest FOV (field of view) available.
- The sample is too X-ray absorbing (dense).
If your sample doesn't fit into the CT scanner, unfortunately, there is not much you can do. You probably need a bigger CT scanner or reduce the sample size.
If the sample fits into the CT scanner but not into the FOV, there are a few things we can consider. Is it really necessary to scan the entire sample? Can you scan just the area of interest and use an FOV smaller than the sample? If you do need to make the whole sample fit in the FOV, the next thing to check is if you are using the largest FOV setting available on your CT scanner. Some scanners have stitching, helical, or offset scan modes that can make the FOV larger than what the detector can cover in a standard scan.

6. Files are too big
7. Analysis is too involved
As much as I want more people to see the potential of X-ray CT and introduce this technology to their research, I don't want you to make the wrong decision and regret it later. I hope this article will help you avoid these common problems. Our team of application scientists can help you if you have any questions or need help deciding if CT is the right solution for you.
