uCT 550
Overview
The uCT 550 is a multi-slice X-ray Computed Tomography (CT) system manufactured by Shanghai United Imaging Healthcare Co., Ltd. It is designed to produce cross-sectional images of the body through computer reconstruction of X-ray transmission data. The system is built on an ultra-low noise Z-Detector and features a 0.5-second rotation speed, offering up to 80 slices for comprehensive imaging.
The uCT 550 integrates advanced technologies to deliver high image quality with reduced radiation dose. Key features include the Z-Detector with ultra-low electronic noise for superior signal-to-noise ratio and detailed images, and the KARL 3D iterative denoising technique which significantly reduces radiation dose while maintaining image quality.
It incorporates an AI-empowered workflow, such as the Easy-Logic Intelligent Prediction Platform, which anticipates user operations to streamline the scanning process and boost daily patient throughput. The system also includes Metal Artifact Correction (MAC) to remove artifacts and a 1024 Reconstruction Matrix for high-resolution images.
The uCT 550 is intended for whole-body imaging, including the head, neck, cardiac, and vascular regions, and supports a wide variety of clinical applications.

What Physicians Need to Know
Leverage the uCT 550's AI-empowered workflow for streamlined patient positioning and optimized scan range selection, which can significantly reduce preparation time and enhance throughput. Utilize AI-driven reconstruction algorithms like KARL 3D and uAI DELTA to achieve high-quality, low-dose images, particularly beneficial for challenging cases involving metal implants or motion. For lung nodule screening, the integrated AI tools can serve as an effective second reader, potentially increasing detection sensitivity and accuracy, thereby assisting in reducing radiologist workload and improving diagnostic confidence. Be aware of the 2-4 minute processing time for AI-assisted lung nodule analysis when planning workflow.
The uCT 550 supports standard DICOM for image output and is designed to integrate with post-processing applications and AI servers. This allows for seamless transfer of acquired CT images for AI analysis (e.g., lung nodule detection) and subsequent archiving in PACS. United Imaging's 'All-in Configurations' and 'Software Upgrades for Life' ensure that all available software features, including AI advancements, are included and updated, simplifying integration and future-proofing the system within existing radiology IT infrastructure.
