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 max. 200mm
GPU based high speed cone-beam reconstruction
- Less than 47sec @ 512³ voxels from 360 projections of 1944×1536 pixels (at the high-resolution mode & off-line mode)
High image quality, Low-dose, High speed system
Physiological monitoring for in-vivo small animal
