Abstract cross-section of the QuantaMax detector: X-ray photons that are converted to an electrical charge by the crystal semi-conductor.

At the heart of NAEOTOM Alpha® is a radically new photon-counting detector. The QuantaMax detector directly converts X-rays into an electrical signal, which is then used to create an image. The energy of each X-ray is measured, so spectral information is available for every scan, and the images are contrast-rich with high spatial resolution at the same dose. Combining the high spatial resolution of the QuantaMax photon-counting detector with our Dual Source temporal resolution enables the visualization of fine details for increased diagnostic confidence. 

 Features & Benefits


Key technologies 

NAEOTOM Alpha with Quantum Technology is the reinvention of computed tomography and offers a radically new way of generating clinical results. It incorporates innovative technologies designed to overcome the limitations of conventional CT scanners.
