Instrumentation

NEW - Scanco µCT50 (Excised Specimens)

  • Max spatial resolution: 2 µm (10% MTF); Max nominal resolution (voxel size) 0.5 µm
  • Voltage: 20-100 kVp; Max current: 200 µA; 3400 x 1200-element detector
  • Optional compression/tension stage can apply up to 500N load (±1%) and 9mm displacement (±0.02mm)
  • Optional temperature stage allows small samples to be heated/cooled ±15°C from ambient temperature
  • Appropriate for all specimens compatible with µCT40

Scanco µCT40 (Excised Specimens)

  • Max spatial resolution: 8 µm (10% MTF); Max nominal resolution (voxel size) 3 µm
  • Voltage: 30-70 kVp; Max current 177 µA at lowest energy; 2048 x 256-element detector
  • Field of view: 10-40 mm diameter × 70 mm length
  • Quantitative analysis of bone architecture (cortical and trabecular measurements)
  • Rodent bone morphometry, fracture repair, tissue engineering constructs
  • Contrast-enhanced imaging of tumors and vasculature
  • High-contrast imaging of heavy metal-stained organs, embryos, marrow adipocytes
  • Select applications in materials science, pharmaceutical manufacturing, and museum/educational pieces
  • Scan time scales with resolution and field of view height. As an example, a set of 4 full-length mouse femurs, at 16 µm resolution, takes approximately 110 minutes of scan time. The same scan at 8 µm resolution takes twice as long.

Scanco VivaCT40 (Live Animals)

  • Field of view: 20-40 mm diameter × 140 mm length
  • Spatial resolution: 10 µm to 40 µm
  • Longitudinal quantitation of bone morphometry (best suited for cranial imaging)
  • Contrast-enhanced imaging of vasculature, tumors, etc.
  • Primarily used for in vivo imaging of mice (or small rats) under isoflurane anesthesia.
  • IACUC approval is required for all procedures involving live animals.
