Frequently Asked Questions


  • What is Multiscale CT?

By bringing together various state-of-the-art CT scanners under one roof, Multiscale CT allows the user to run CT scans at various spatial resolutions – ranging from mm to sub 50nm. The concept is best understood by the figure below (click to view full size), which shows the typical samples at different resolutions and also the CT scanner usable at that scale.

SAMCT Poster1
Relatively thick samples (with thickness of several mm) to thin samples (few microns thick) may be imaged at extremely high resolution. This is made possible by the bringing together of various CT scanners under one roof:

  • conventional scanners with mm spatial resolution

o   suitable for imaging human/animal organs and extremities

  • micro-CT scanners of 0.5-20μm resolution

o   suitable for imaging cells

  • state of the art X-ray nano-CT having sub 50nm spatial resolutions

o   which may be used to depict ultrafine details of DNA and chromosome

  • What are the scanners available at SAM-CT?

See the Scanner List webpage.

  • How can I schedule time with the scanners?

To schedule a time to perform a scan, please visit the Schedule webpage.

  • How much does it cost to use the facility?

  • How is SAM-CT Facility contributing to the advancement of research?

The SAM-CT facility is a regional center with many users, and has accelerated progress in many fields such as medicine, biology, nanotechnology, materials, and energy. Having the only 50nm resolution CT system on the East Coast and the only CT system with local focusing and accurate interior reconstruction capabilities in the world, this facility is invaluable to both institutions and industries in the US.

  • Do I need to be trained to use the scanners?

Yes, please visit the Training webpage.
