They don't mention anything on their website, but I guess - from looking at their machine - that they use an x-ray source which goes to the range of 150kV, since they also show larger items with more metal volume being scanned. *source: I work with two of the machines here: https://www.bruker.com/en/products-and-solutions/microscopes/3d-x-ray-microscopes.html https://www.bruker.com/en/products-and-solutions/microscopes... (and one more from Bruker which is so old that they don't show it on their website anymore).

I need a 225 kV (or higher) system with good 3D tomography. Any idea what the most cost effective option is?

  What is 'good' tomography? High resolution, fast scanning or only imaging a certain kind of samples? I presume you're not scanning biological material with such a high acceleration voltage, so I'd look into NDT systems from https://www.nikonmetrology.com/en-us/x-ray-ct https://www.nikonmetrology.com/en-us/x-ray-ct or https://www.zeiss.com/microscopy/en/products/x-ray-microscopy.html https://www.zeiss.com/microscopy/en/products/x-ray-microscop...

    Good tomography meant that we get useful solid models in a form that is easy to interact with and pull numeric dimensional data from. Is the software separate from the hardware, or coupled? Good resolution is also important. Say I want to analyze something the size of a can of soup and get to tens of microns resolution. Zeiss and Nikon are not cheap options. Is anyone out there bringing the cost down?

The Bruker machine I use can do ~15 cm diameter samples at ~40 um voxel size, so that’s something that should be possible with any machines. > Bringing cost down MicroCT machines are not cheap, but - as I’ve seen from our buying process - all in the same ballpark. You might not need your own machine, but use a ‘supplier’ for CT Scans in a case-to-case basis.

  What do you want to scan?
