Siemens Naeotom Alpha with Quantum Technology

National Jewish Health is one of the first organizations in the western United States to have the Naeotom Alpha CT technology. This is a photon counting CT (PCCT). It is a fundamental breakthrough in CT technology that provides improved spatial resolution, less image noise, a reduced patient radiation dose and true spectral imaging at multiple photon energy thresholds.  


  • Ultra high resolution to visualize the finest details for high diagnostic confidence in evaluating patients with interstitial lung disease, bronchiectasis, coronary diseases and other unusual airway diseases.
  • Reduces dose for screening and dose-sensitive patients.
  • Improved image contrast.
  • Highly detailed reporting to patients and providers.
  • Follows the progression of lung nodules and other chronic respiratory disorders and cancers.


Siemens Definition AS+ 128 Slice


  • Reduced Scan Time - With its 128 slices/per rotation, this scanner has a high rotation speed of 300 milliseconds. Because of the high number of detectors, the scanner can acquire more images in a shorter period of time thus reducing the chance of blurriness due to patient movement.
  • CTAs- Capable of performing CT angiography (a scan focusing on the blood vessels) in just 4 seconds
  • RealTime Fluoroscopy - Can be used for performing fluoroscopy guided biopsies.
  • Bariatric Imaging - This scanner also has a high capacity table for scanning heavier patients up to 600 lbs.
