Micro-computed tomography (CT) advances biomedical imaging for drug discovery and disease monitoring. Micro-CT provides high-resolution 3-D imaging of small animals and organ biopsies, bridging a gap between microscopy and clinical CT.

Area of Science:

  • Biomedical imaging
  • Medical physics

Background:

  • Growing interest in tomographic imaging for drug discovery, cancer detection, and disease monitoring.
  • Micro-computed tomography (CT) scanners are scaled-down versions of clinical CT scanners.
  • Mini-CT provides 3-D imaging of small animal torsos at 50-100 microm resolution.

Purpose of the Study:

  • To highlight the capabilities of micro-CT in biomedical applications.
  • To explain the resolution capabilities of micro-CT compared to other imaging modalities.
  • To underscore the role of micro-CT in drug discovery and disease research.

Main Methods:

  • Utilizing micro-CT scanners for imaging small animal models and organ biopsies.
  • Achieving spatial resolutions from cellular (20 microm) down to subcellular (1 microm) dimensions.
