SIEMENS VETERINARY CT
NAEOTOM Alpha
The Siemens NAEOTOM Alpha is the world’s first photon-counting CT scanner, a fundamental reimagining of how CT works. By counting individual X-ray photons rather than measuring integrated energy, it delivers spectral information in every scan at every dose level, with zero electronic noise, ultra-high spatial resolution, and the ability to reduce contrast agent volume by up to 50%. For veterinary practices at the frontier of diagnostic imaging, nothing else compares.

CLINICAL APPLICATIONS
What this system is built for
The NAEOTOM Alpha is built for veterinary institutions that demand the absolute frontier of CT capability, delivering photon-counting spectral data, ultra-high resolution, and dual-source speed in every single acquisition.
Spectral & material characterization
Photon-counting technology delivers inline spectral results, monoenergetic images, material maps, and effective atomic number in every scan without mode switching, enabling precise tissue and material characterization at no additional dose.
Cardiac imaging
Dual-source design achieves 66 ms native temporal resolution, the highest available in clinical CT, enabling definitive cardiac CTA and functional studies even in patients with elevated or irregular heart rates.
Ultra-high resolution imaging
With detector pixels 9× smaller than conventional CT, the NAEOTOM Alpha resolves fine anatomical structures, inner ear, bone microarchitecture, and small vessel detail at a level previously only possible with dedicated micro-CT systems.
Research & advanced diagnostics
Veterinary teaching hospitals and research institutions use the NAEOTOM Alpha to pioneer new imaging protocols, from quantitative iodine mapping and virtual non-contrast imaging to spectral bone analysis and novel contrast agent evaluation.
