NAEOTOM Alpha.Peak/ NAEOTOM Alpha
Overview
The NAEOTOM Alpha.Peak, part of the NAEOTOM Alpha class, is the world’s first commercially available photon-counting computed tomography (CT) scanner, developed by Siemens Healthineers. It represents a significant advancement in medical imaging by directly converting X-rays into electrical signals, allowing for individual photon counting. This revolutionary QuantaMax detector technology eliminates electronic noise and provides intrinsic spectral capabilities, leading to superior image quality. The system delivers high-resolution images with slice thickness down to 0.2 mm, even for patients with high BMI, while significantly reducing radiation dose compared to conventional CT scanners.
NAEOTOM Alpha.Peak integrates advanced AI-powered workflows, including myExam Companion and Recon&GO, to streamline scanning procedures, automate post-processing tasks, and assist radiologists in reading cases. Its Dual Source technology enables unmatched speed with a temporal resolution of 66 ms and scan speeds up to 737 mm/s, crucial for challenging imaging tasks like cardiac scans. This combination of high resolution, low dose, spectral information, and intelligent automation aims to enhance diagnostic confidence, expand patient reach, and provide meaningful answers across various clinical fields.

What Physicians Need to Know
Leverage the AI-powered workflows and intrinsic spectral capabilities of NAEOTOM Alpha for enhanced diagnostic confidence and efficiency. The system's ability to provide high-resolution images at low doses, coupled with spectral information in every scan, can significantly improve the evaluation of complex cases, such as highly calcified coronary arteries, stroke, trauma, and oncology. Utilize `myExam Companion` for streamlined scanning and `Recon&GO` for automated post-processing to reduce manual tasks and inter-operator variability. The interactive spectral imaging tools enable on-the-fly analysis of tissue characteristics, which can be crucial for precise decision-making and potentially expanding the range of patients who can undergo CT examinations without the need for sedation or beta-blockers.
The NAEOTOM Alpha class fully supports DICOM standards for image output. Seamless integration with Picture Archiving and Communication Systems (PACS) is a key focus, with ongoing collaborations (e.g., with Sectra) to allow direct access to Siemens Healthineers' advanced spectral post-processing tools within existing radiology diagnostic applications. This eliminates the need for radiologists to switch to separate workstations or proprietary software for advanced analysis. The system's underlying software, `syngo CT VB10 (SOMARIS/10 syngo CT VB10)`, manages patient data, scan control, image reconstruction, and archiving, ensuring a cohesive workflow.
