NFR Polaris-G90
Dedicated micro-CT scanner for in-vivo small animal imaging
  • NFR Polaris-G90 sets the standard for in-vivo preclinical micro computed tomography.
  • NFR Polaris-G90 range balances between short scan times with good low-contrast and high spatial resolution.
  • Precision Gantry Rotation System
  • To allows for continuous rotation a slip-ring connects the stationary part of the gantry with the x-ray tube and the detectors.
  • Variable Magnification System
  • Magnification 1.4x ~ 10x, Sample size 100mm ~ 10mm, scan length 200mm
  • GPU based high speed cone-beam reconstruction
  • Less than 47sec @ 5123 voxels from 360 projections of 1944x1536 pixels (at the high-resolution mode & off-line mode)
  • High image quality, Low-dose, High speed system
    Physiological monitoring for in-vivo small animal
