μCT

Perkin-Elmer QuantumGX

The Quantum GX offers the highest resolution among all the microCT scanners for in vivo imaging. It is suitable for all analytical CT applications and features cardiac gated imaging, an adjustable bore size that enables imaging of a wide range of species up to rabbits in size, and an energy range of 20-90 kV.

The system has three modes: high resolution, high speed and standard modes. As an example, in the high-resolution mode, a 4.5 μm voxel size resolution can be attained at a 36 x 36 mm FOV, while a 9 μm voxel size resolution can be attained at 72 x 72 mm FOV.

The Quantum GX is the fastest microCT system with industry leading scan times of 8 seconds in the high-speed mode. The sub-reconstruction features allow users to reconstruct an acquired image at higher resolution without the need to rescan the subject thus reducing both the time needed for a study and the radiation exposure to the animal. The Quantum GX has the lowest radiation dose exposure of all microCT scanners on the market due to the use of a CMOS detector.
