Siemens Healthineers expands Photon-Counting CT portfolio with FDA approval

USA – Siemens Healthineers has received FDA clearance for its expanded Naeotom Alpha series of photon-counting computed tomography (CT) scanners, introducing new models designed to enhance diagnostic imaging capabilities across various clinical settings. ​

The newly approved lineup includes: ​

• Naeotom Alpha.Pro: A dual-source system offering a scan speed of 491 mm/sec, beneficial for pediatric and cardiology patients by reducing breath-hold times and minimizing the need for sedation or beta-blockers. ​
• Naeotom Alpha.Prime: The first commercially available single-source photon-counting CT scanner, scanning at 345 mm/sec, equipped with automation features to streamline workflows. ​

These additions complement the existing Naeotom Alpha.Peak (formerly the original Naeotom Alpha), which remains the flagship model with the fastest scan speed of 737 mm/sec and Quantum HD resolution at a 0.2 mm slice thickness. ​

Photon-counting CT technology enables direct measurement of individual X-ray photons, enhancing image resolution and functional imaging while reducing radiation exposure.

This advancement allows for improved visualization of small anatomical structures with fewer artifacts compared to conventional CT scanners. ​

Matthew Dedman, head of computed tomography at Siemens Healthineers North America, stated, “By introducing our Naeotom Alpha class of photon-counting CT scanners, Siemens Healthineers delivers on what we see as our responsibility: to broaden the availability of this technology and enable customers to provide its clinical benefits to as many clinicians and patients as possible.”​

The Naeotom Alpha.Prime integrates Siemens Healthineers’ AI-powered myExam Companion interface, assisting with exam setup, image acquisition, and post-processing.

This feature aims to standardize and simplify CT operations across different patient types and procedures, enhancing efficiency and consistency in imaging practices. ​

With over a million patient scans completed worldwide since the Naeotom Alpha’s initial launch in 2021, the expanded lineup signifies Siemens Healthineers’ commitment to advancing CT imaging technology and making high-resolution, low-dose imaging more accessible to diverse healthcare environments. ​
