NAEOTOM Alpha.Prime
Overview
NAEOTOM Alpha.Prime, from Siemens Medical Solutions USA, is a groundbreaking single-source photon-counting Computed Tomography (CT) scanner. It represents a new benchmark in medical imaging, offering unprecedented clarity and detail in diagnostic and interventional processes. Unlike conventional CT, this system directly counts each X-ray photon, enabling high-resolution imaging with significantly reduced radiation doses. It integrates advanced Artificial Intelligence (AI)-powered workflows, such as myExam Companion and zero-click Recon&GO, to streamline scanning procedures, optimize image acquisition and reconstruction, and enhance post-processing and evaluation. This technology provides intrinsic spectral sensitivity and Quantum HD resolution, allowing for the visualization of minute structures and comprehensive insights across a wide range of clinical applications. It is designed to empower healthcare professionals with precise diagnostic information for confident decision-making and improved patient care.
