DigiM works with clients on x-ray micro-computed tomographic imaging using state-of-the-art laboratory and synchrotron systems. DigiM focuses on resolutions in the range of 30nm to a few micrometers.


The term MicroCT is used generally to include MicroCT, NanoCT, Synchrotron, and X-ray Microscope. Please see the diagram below for a comparison of MicroCT 3D imaging technology with other techniques, the resolution ranges each technique covers, and recent industrial consolidations. DigiM has experiences with images from all these manufacturers, and played critical roles in the design and development of several software platforms they bundle.

In addition to working on clients’ samples to get high quality MicroCT images, DigiM can also play an instrumental role in the decision-making process when clients are inclined to purchase the equipment in-house. DigiM can help with vendor evaluation, workflow evaluation and laboratory setup. DigiM provides a complete solution to fit our customers’ diverse and unique needs.

MicroCT’s advantages and challenges    

Pros Chanllenges
  • Nondestructive
  • 3D
  • Larger field of view (comparing to EM based technique)
  • Possible to support dynamic imaging with sample under changing thermal, mechanical, electrical constraints.
  • Intensity calibration from sample to sample
  • Beam hardening
  • Scanning time and Signal-to-noise-ratio balance
  • Massive amount of result data stretching storage and computation resources.
