Naeotom Alpha

NAEOTOM Alpha® with Quantum Technology

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 never-before seen range of clinical options and breakthrough consistency – for potentially scanning previously excluded patients and confident clinical decision making.

Experience a defining moment in computed tomography.
