Unprecedented. 
Unrivaled. 
Unstoppable.Photon-counting CT is NAEOTOM®

In November 2021, a new era began
 
NAEOTOM Alpha®, the world’s first photon-counting CT scanner, entered the stage. Since then, it has taken the world of computed tomography by storm. As Siemens Healthineers' photon-counting technology is going into its third year on the market, countless publications are available and hundreds of thousands of patients have been scanned with NAEOTOM Alpha. 

It is this experience that sets us apart. Siemens Healthineers' photon-counting technology is established, proven at scale, and delivering real-world results. It is safe to say that there has been nothing like it in the past and that there is nothing that compares to it now. And this motivates us to keep pushing forward. Join us in extending this lead in computed tomography together.

The technology behind Siemens Healthineers' photon-counting is game changing and unprecedented. Nowhere else will you find such a combination of image resolution, low radiation dose, spectral information, and speed – proven in clinical practice, ready for routine, and perfectly attuned.

Twice the resolution. New level of dose performance*

Compared to conventional CT scanners, Siemens Healthineers' photon-counting offers twice the resolution and brings a new level of dose performance.

Spectral imaging independent of resolution, scan speed, and FoV

Every scan you perform is a spectral scan, which means you get spectral maps independent of resolution, scan speed, or field of view.

Fastest scan speed in 
the world** 

On top of that, our photon-counting scanner NAEOTOM Alpha has simply the world’s fastest scan speed.
