NAEOTOM Alpha

PURE Lumen

The artifacts resulting from calcifications in arteries can make the valuation of the true lumen of a vessel impossible. PURE Lumen removes these calcifications based on the spectral information contained in every voxel of the image.

• Evaluate even heavily calcified vessels 
• Create virtual non-calcium maps 
• Perform coronary CTA exams in patients with high CaScore

Low-Dose Performance

The QuantaMax detector can completely eliminate electronic noise, leading to improved signal- to-noise ratio that can be utilized to significantly reduce dose. All this while still delivering high resolution and spectral information in each scan.

• Noise-free images even in low-dose applications
• Further reduce dose for screening and dose-sensitive patients
• Retrospective spectral evaluation of incidental findings in screening scans

Improved Image Contrast — Potential Reduction of Contrast Media Volume

With a contrast-to-noise ratio significantly higher than electron-integrating detectors, NAEOTOM Alpha improves visibility of anatomies enhanced by contrast media. Monoenergetic images can be used to further enhance the contrast.

• Visualize enhancement in fine anatomical structures
• Potentially reduce the amount of contrast media

Spectral Imaging at Dual Source Temporal Resolution

As a Dual Source system, NAEOTOM Alpha provides a temporal resolution down to 66 ms. Offering the full range of spectral imaging evaluation at this speed paves the way for diagnostic procedures that were previously unthinkable.

• Spectral imaging for cardiac scans
• Evaluate coronary arteries and get spectral maps (e.g., iodine concentration) in the same scan

Spectral Imaging at High Spatial Resolution

With NAEOTOM Alpha, spectral maps are available with more detail than ever before — down to a slice thickness of .4 mm. This enables functional evaluation with high precision.

• Detect fine lesions in the liver 
• Evaluate spectral bone marrow edema 
• Evaluate lung perfusion defects based on detailed iodine maps

Spectral Imaging at Turbo Flash Speeds

As a Dual Source system, NAEOTOM Alpha scans at a maximum pitch of 3.2. Even at the highest scan speed, the system delivers results with full spectral imaging analysis options.

Spectral imaging:

• For high-pitch CTA exams
• In patients who cannot hold their breath
• In pediatric patients without sedation

Monoenergetic Images as Default Image Type

For every scan, NAEOTOM Alpha produces monoenergetic images independent of scan parameters, allowing radiologists to tailor exams to the needs of the patient without compromising on consistency or comparability.

• Analyze, evaluate and compare scans using ideal monoenergetic images for the clinical question at hand

Stable Hounsfield Values

Moving toward quantitative CT evaluation and radiomics, radiologists and referrers need to rely on the stability of their measurements. Photon-counting CT provides this stability in contrast to conventional computed tomography.

• Rely on quantitative and reproducible HU measurements even in low-dose scans

Intuitive Operation. Uncomplicated.

NAEOTOM Alpha redefines how sophisticated CT technology can be utilized. It marks the first time Siemens Healthineers provides proven usability features in a premium, high-end CT. The system supports and guides users throughout the scanning workflow, while AI-enabled solutions help radiologists when reading cases.

Unleash the full power of NAEOTOM Alpha, safeguard consistency at high quality levels, and deduct powerful answers for patients and referrers. Powerful technology. Easy to use.
