Holes in thinner plastic scans

[[Br...]]

Is there a magic formula for scanning thinner plastic samples, without ending up with holes in the mesh? I seem to go back and forth in troubleshooting this issue. Less kV, more exposure and more image averaging seem to work on some projects, more kV with less exposure works better at other times. Struggling with a project currently, no matter the settings, seem to be having issue getting decent polygonization. Have attempted to utilize multiple variations of pol. settings as well. Have as much angle on the sample as I can manage. I'm left wondering if there was a "standard" setting to begin with regarding.

Thanks as always to the group for any assist.

Should add--Metrotomm800 is the scanner in question

 I have scanned A LOT of small plastic samples of all densities with our Metrotom 6 Scout. Your machine should be able to handle this just fine. Is "Use reliable surfaces only" unchecked? What does your volume look like (any problems visible)? What software are you using? Make sure beam hardening correction is off. When you double click the volume, a menu on the right side of the screen pops out. Go to "Display" and change your absorption length to a smaller number to increase the amount of material visible in the volume.

Volume has a lot of thin areas as well. I will look at the Metrotom, I have not purposefully enabled beam hardening. I had not tried/ was unaware of the absorption length setting, will definitely give that a try, appreciate the suggestions, will report back on results!
