CT redefined.

NAEOTOM Alpha^® with Quantum Technology

Photon-counting CT

We are proud to introduce the world’s first photon-counting CT. NAEOTOM Alpha® with Quantum Technology is nothing less than the total reinvention of computed tomography.

Based on the revolutionary direct signal-conversion of its QuantaMax detector, NAEOTOM Alpha offers high-resolution images at minimal dose, spectral information in every scan, and improved contrast at lower noise.

Benefit from a never-before seen range of clinical options and breakthrough consistency – for potentially scanning previously excluded patients and confident clinical decision making.

Experience a defining moment in computed tomography.

Impressive details. Unveiled.
Patient reach. Unlocked.
Meaningful answers. Uncompromised
Consistent precision. Unvaried.
Intuitive operation. Uncomplicated.

Important to know about NAEOTOM Alpha

: NAEOTOM Alpha has CE-label and FDA 510(k) clearance.
: Visits to a small number of reference sites in Europe and USA will be possible after RSNA. To arrange a visit, please contact your local Siemens Healthineers sales organization.
: The new name NAEOTOM reflects the disruptive nature of the introduction of photon-counting CT. It is a fundamental change how a CT operates and produces images.

NAEOTOM Alpha is not commercially available in all countries. Due to regulatory reasons, its future availability cannot be guaranteed. Please contact your local Siemens Healthineers organization for further details.
