uCT 780

The uCT 780 Computed Tomography X-Ray System, enhanced with AI-based Deep Recon (DELTA) and uWS-CT-Dual Energy Analysis software, is designed to generate high-quality cross-sectional images across various body regions. This system's core methodology involves advanced image reconstruction and dual-energy processing, demonstrated to achieve equivalent or superior diagnostic image quality at potentially lower radiation doses, particularly for applications like low-dose CT lung cancer screening.

The Shanghai United Imaging Healthcare Co., Ltd. uCT 780 Computed Tomography X-Ray System, including its uWS-CT-Dual Energy Analysis software, is designed for producing cross-sectional images of various body parts such as the head, neck, cardiac, and vascular regions. A key application is low-dose CT lung cancer screening, aiding in early nodule detection. The integrated Dual Energy Analysis software further enhances diagnostic capabilities by processing images acquired at different energy spectra to provide insights into the chemical composition of scanned tissues. Recent modifications to the system's AI-based Deep Recon (DELTA) feature have undergone rigorous performance testing, demonstrating significant improvements. Bench tests using phantoms revealed enhanced image quality metrics, including reduced noise, improved low contrast detectability, and better spatial resolution, suggesting the potential for diagnostic imaging at lower radiation doses. Clinical evaluations, supported by a radiologist reader study, confirmed that the modified system delivers image quality equivalent to or superior to a predicate device. Users are advised to collaborate with radiologists and physicists to establish appropriate dose protocols, especially when utilizing the DELTA feature or for pediatric patients, to ensure optimal diagnostic image quality.
