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
