NAEOTOM Alpha®
with Quantum Technology

The world’s first photon-counting CT

NAEOTOM Alpha VA50 Product Image

CT redefined.

NAEOTOM Alpha® with Quantum Technology, the world's first photon-counting CT, 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 range of clinical options and breakthrough consistency never seen before – for confident clinical decision-making and the potential to scan previously excluded patients.

Experience a defining moment in computed tomography.

What is photon-counting CT?  

NAEOTOM Alpha Photon-Counting CT Detector

With photon-counting CT, we have developed a radically new technology for clinical routine. At its core is a new kind of detector that is substantially different from a standard energy-integrating detector.

These photon-counting detectors have the potential to overcome the limitations of current CT detectors, by providing CT data at high spatial resolution, without electronic noise, and with inherent spectral information.

 

See fine details without compromises

NAEOTOM Alpha redefines how high resolution and inherent spectral information can be utilized for multiple myeloma patients to detect small osteolytic bone lesions and precisely assess their status. Discover how Prof. Konstantin Nikolaou and Prof. Claudia Lengerke benefit from a new level of detail for their clinical decisions, while keeping dose to a minimum.

High resolution at low dose

With a slice thickness of 0.4 mm and an in-plane resolution of 0.24 mm in standard scan protocols, NAEOTOM Alpha provides an impressive level of detail at full dose efficiency.

  • High resolution in all standard native protocols
  • High resolution in all standard CT angiography protocols
  • High level of detail for evaluating fine structures in all anatomical areas

Redefining CT in Cardiology

Watch what Joseph Schoepf, MD, Professor of Radiology, Medicine, and Pediatrics, and Richard Bayer, MD, Cardiologist and Association Professor of Medicine and Radiology, both at the Medical University of South Carolina (MUSC), have to say about the range of patients that can be addressed with the NAEOTOM Alpha.

NAEOTOM Alpha Low-Dose Performance

Low-dose performance

The QuantaMax detector is able to completely eliminate electronic noise. This leads to improved signal-to-noise ratio, which can be utilized for significant dose reduction. At the same time, the scanner still delivers high resolution and spectral information in every 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

Provide meaningful answers to all oncological cases

Learn how Prof. Claudia Lengerke and Prof. Konstantin Nikolaou improve oncologic body imaging for different patient groups and without any compromise on scan speed, spatial resolution or spectral information. NAEOTOM Alpha provides all required CT information in one scan for a powerful tumor lesion depiction and detection of small lesions.

Providing non-invasive answers – clearly and accurately

Discover how Prof. Joe Schoepf and Dr. Richard Bayer benefit from getting more answers with each scan of NAEOTOM Alpha.

Bringing all relevant CT results to one single scan.

Explore Prof. Martine Rémy-Jardin and Prof. David Launay's opinions on how NAEOTOM Alpha is deeply impacting clinical decision making for pulmonology.

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
  • Spectral imaging in patients who cannot hold their breath
  • Spectral imaging in pediatric patients without sedation

Precision and consistency by bringing spectral information into clinical routine

Learn how Prof. Claudia Lengerke and Prof. Konstantin Nikolaou bring spectral information into their routine workup for iron quantification to diagnose relevant complications in oncologic patients.

Diagnostic consistency in pulmonology throughout the whole patient journey

See how Prof. Martine Rémy-Jardin and Prof. Launay talk about the advantages of using NAEOTOM Alpha for exquisite delineation of lung fibrosis even in obese patients.

NAEOTOM Alpha Monoenergetic Images as Default Image Type

Monoenergetic images as default image type

For every scan, NAEOTOM Alpha produces monoenergetic images that are independent of scan parameters. This allows radiologists to tailor exams to the needs of the patient without compromising on consistency and comparability.

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

Pulmonology

NAEOTOM Alpha offers an easy and streamlined way to get quantitative information in addition to morphology. By matching the appropriate protocols to patients and by combining all necessary acquisitions into a single scan, NAEOTOM Alpha enables smart navigation through the diagnostic pathway.

Oncology

The standard monoenergetic images provided by NAEOTOM Alpha allow radiologists to eliminate one source of imprecision. Comparability across several acquisitions allows users to confidently determine that changes between scans are a result of the therapy or the physiology of the lesion, and not driven by inconsistencies in imaging parameters.
