What Physicians Need to Know

DICOM Support & Standards
The uCT 550 system reconstructs images in DICOM format, which can be used by post-processing applications.
PACS Integration Method
All studies were reviewed on a PACS workstation.
Reading Room Workflow Impact
The uCT 550 is designed to automate many tasks, streamlining workflow and supporting high daily patient throughput. Its AI-empowered workflow enables fast and reproducible positioning with a single click and automatically selects the scan range based on the scout, optimizing image quality and dose. The Easy-Logic intelligent prediction platform anticipates the next user operation, preparing the system for subsequent phases like tube and gantry preparation and data pre-processing, which ensures a seamless and streamlined workflow.
AI Model Architecture (deep learning approach)
The uCT 550 incorporates AI-based deep learning algorithms. DELTA (Deep learning trained algorithm) leverages an extensive training dataset and a sophisticated 3D neural network for image reconstruction, aiming for sharper, more detailed images at lower radiation doses. The system also features uAI Vision 3D camera and AI-workflow. United Imaging's CT systems integrate advanced AI algorithms into every stage of the scanning process to deliver faster, clearer, and more accurate results. AI-driven analysis enhances lesion detection, anatomical segmentation, and clinical decision support.
Processing Speed (per study)
The uCT 550 has a 0.5-second rotation speed. The large heat-capacity tube with 815kHU/min heat dissipation capability promotes fast workflow. Scan times can be as low as 10.5 seconds per phase for consecutive CTA+CTV+CTU, with a scan range of 1524mm completed in 26.6 seconds.
FDA Clearance Pathway (510k/De Novo)
The uCT 550 received 510(k) clearance (K181414) as a Class II Computed Tomography X-ray System (Product Code JAK). It was determined to be substantially equivalent to legally marketed predicate devices.
Supported Modalities (CT/MRI/X-ray/US)

Sensitivity & Specificity Data
In a study assessing lung nodule detection, the performance of AI was found to be better than radiologist performance across all nodule categories (solid, subsolid, and calcified), suggesting AI was more sensitive and accurate. The system aims to reduce radiation dose by up to 80% and image noise by up to 98% while maintaining image quality and low contrast detectability.
RSNA/ACR Validation
A clinical evaluation was conducted through a reader study where board-certified U.S. radiologists scored image quality on a five-point scale for noise, image structure fidelity, and overall image quality.
Physician Tip

The uCT 550 offers advanced imaging capabilities with a focus on low-dose protocols and high image quality, which can be particularly beneficial for sensitive patient populations and for follow-up studies requiring reduced radiation exposure.

The system's ability to handle patients with metal implants and perform various advanced applications like CTA and calcium scoring expands its clinical utility. Physicians should leverage the AI-assisted features for improved nodule detection and consider the benefits of reduced radiation dose in patient management.

The uCT 550 produces images in DICOM format, ensuring compatibility with standard PACS systems for image archiving and post-processing. Its AI-driven features are integrated into the workflow to optimize image acquisition and reconstruction. The 'All-In Configurations' and 'Software Upgrades for Life' policies suggest that future software enhancements and AI applications will be readily available, potentially simplifying long-term integration and upgrades within a healthcare IT ecosystem.

Frequently Asked Questions

The uCT 550 incorporates AI-empowered workflows for efficient and reproducible patient positioning, automatically selecting scan ranges to optimize image quality and radiation dose. It also utilizes a deep learning trained algorithm called DELTA, which leverages a 3D neural network and extensive datasets to produce sharper, more detailed images with reduced radiation dose and noise.
The uCT 550 prioritizes patient safety with advanced dose reduction technologies, including a 70 kVp scan mode and Auto ALARA kVp, which automatically selects tube voltage based on patient size and protocol to optimize dose distribution. The system's Z-Detector and iterative denoising algorithms like KARL 3D also contribute to maintaining high image quality at lower radiation levels.
While the uCT 550 offers advanced imaging capabilities, like all CT systems, it involves ionizing radiation, which necessitates careful consideration of the risk-benefit for each patient, especially in pediatric or pregnant populations. Additionally, CT generally provides inferior soft tissue contrast compared to MRI, which may limit its utility in certain pathologies like brain lesions or ligament tears.
Alternatives to the uCT 550 (an 80-slice CT scanner) include other CT systems from manufacturers like GE, Siemens, Toshiba (Canon), and Philips, which offer various slice counts and features. For instance, higher-slice CTs (128+ slices) may offer faster speeds and more advanced cardiac imaging, while entry-level CTs (16-64 slices) might be more cost-effective for basic scanning. Photon-counting CT (PCCT) is also an emerging technology that promises improved image quality and dose efficiency.
While specific pricing for the uCT 550 is not publicly disclosed, United Imaging offers a 'uCT 550 Advance' program that includes collaborative room planning, a full coverage warranty, and a 5-year service bundle (excluding the CT tube) at a competitive purchase price. The company also provides 'Software Upgrades for Life,' meaning all future software upgrades are included at no additional charge for the system's lifetime.
