The New Benchmark
Built for versatile performance, NAEOTOM® Alpha.Prime brings Quantum Technology into clinical routine.
- A new imaging standard to support lesion detection, characterization and treatment planning
- AI-powered workflows speed up processes
- Quantum Spectral Imaging and Quantum HD resolution in single source CT for the first time

Benefit more patients
More details in neurology
The unique 0.2 mm slice thickness of NAEOTOM Alpha.Prime with Quantum HD provides high accuracy in neurology and can help change patient diagnoses, from the assessment of stroke, aneurysm, CSF venous fistula or the inner ear.
Consistent findings in oncology
Quantum Technology supports better visibility for tumor detection, characterization and monitoring. Solutions for CT-guided interventions or Radiation therapy enable treatment planning, biopsies or ablations.
Empower users with AI
myExam Companion delivers intelligent imaging with individually guided scans that optimize procedures to help leverage the full potential of the scanner. Automated AI-driven workflow solutions enable a faster workflow and utilize zero-click Recon&GO to create the desired clinical operation.
Scale with photon-counting CT
Whether you are starting your journey with photon-counting CT or expanding on the profound clinical impact you have achieved with NAEOTOM Alpha, NAEOTOM Alpha.Prime enables you to elevate care and broaden access to photon-counting CT for a wider range of patients.
Unstoppable in the ED
In the ED, time is of the essence. The speed and reliability of NAEOTOM Alpha.Prime can help trauma patients when their lives depend on it. The user-friendly features of AI-powered myExam Companion help technologists work more efficiently and position patients quickly. A lower dose for polytrauma patients is an added benefit.
