uCT ATLAS Astound with uWS-CT-Dual Energy Analysis
Overview
The uCT ATLAS Astound with uWS-CT-Dual Energy Analysis is an advanced multi-slice computed tomography (CT) X-ray system developed by Shanghai United Imaging Healthcare Co. It integrates cutting-edge image acquisition hardware, reconstruction, and dual-energy analysis software. This system is designed to produce cross-sectional images of the whole body through computer reconstruction of X-ray transmission data. It features an ultra-wide 82 cm bore and a 700 lbs (318 kg) maximum table load capacity, accommodating a wide range of patients. The uCT ATLAS Astound incorporates AI-empowered workflows, including the uAI Vision 3D camera for intelligent patient positioning, scanning, and processing, aiming to provide an efficient, standardized, and personalized scanning experience while reducing radiation dose. The uWS-CT-Dual Energy Analysis is a post-processing software package that utilizes images acquired with different tube voltages and/or currents to visualize information based on varying attenuation coefficients of anatomical regions, providing insights into chemical composition.

What Physicians Need to Know
Leverage the AI-empowered workflow, including intelligent positioning and advanced reconstruction (Deep IR/uAI AI-IR), to optimize image quality at reduced doses, especially for challenging cases like cardiac imaging with high heart rates or patients with high BMI. Utilize the uWS-CT-Dual Energy Analysis for enhanced tissue characterization. The rapid scanning speed and one-beat cardiac capabilities are particularly beneficial for pediatric, trauma, and cardiac patients, minimizing motion artifacts. The 'Software Upgrades for Life' ensures continuous access to the latest advancements, allowing for expanded clinical services without additional software investment.
The system is designed to integrate into existing radiology workflows, implicitly supporting DICOM for image transfer and requiring seamless connectivity with PACS for efficient image archiving, retrieval, and post-processing. Its AI-driven features are integrated directly into the scanner's workflow, streamlining the acquisition and reconstruction process.

What the Web Says
The United Imaging uCT ATLAS Astound with uWS-CT-Dual Energy Analysis is a computed tomography (CT) x-ray system designed for whole-body imaging, including head, cardiac, and vascular applications. It aims to provide exceptional image quality at a low radiation dose and features AI-powered workflows for efficiency. The dual-energy analysis software enhances diagnostic accuracy by differentiating materials based on their attenuation coefficients at different energy levels.
Overall: PositiveStrengths
- Exceptional image quality at a low radiation dose.
- Fast scanning capabilities, particularly beneficial for cardiac, dynamic whole organ, and vascular imaging.
- AI-empowered workflow for efficient, standardized, and personalized scanning.
- Ultra-wide 82 cm bore and 700 lbs table weight capacity accommodate a wide range of patients, including larger individuals and those in trauma.
- Dual-energy analysis provides better diagnostic performance by differentiating materials and potentially reducing contrast agent use.
- All advanced applications and post-reconstruction analysis software, along with software upgrades for life, are included.
Limitations
- One review noted that the predicate device could use a dual energy function on both axial and helical scan modes, but the proposed device only on helical scan mode, though this difference was not deemed to raise new safety and effectiveness concerns.
- Some dual-energy CT systems, depending on their technology, may have limitations such as a restricted field of view for dual-energy imaging in larger patients or require specific scan protocols that increase scan time.
- The increase in images and data from dual-energy CT can present workflow challenges.
- Limited public reviews from physicians, healthcare IT, tech reviewers, Reddit, G2, and Capterra were found, making a comprehensive sentiment analysis challenging.
