Carbon nanotube (CNT) based microCT imaging systemCNT_CT.jpg

The CNT-based microCT system was built by Dr. Otto Zhou’s lab at the UNC physics Department. The unique feature of this microCT is the carbon nanotube based X-ray source, which offers many attractive features including electronic programmability and fast switching. It is perfect for a mouse lung imaging study.

Main advantages of the system include:

  • System can provide high resolution (<100 mm)
  • Prospective gating for mouse lung or cardiac imaging with much less dose
  • CT X-ray current: 0 – 1.5 mA
  • CT X-ray source energy: 50kVp
  • Focal Spot Size: 93mm x 109 mm
  • 39mm x 39mm FOV
  • Cone beam Feldkamp reconstruction algorithms 

Sample studies

  • Mouse lung imaging on genetically engineered mouse lung cancer model
  • Mouse cardiac imaging
  • Mouse colonography on genetically enginnered mouse colon cancer model
