With 2 × 16 cm wide Z-axis coverage, uCT SiriuX Ultrix™ combines ultra-fast temporal resolution with whole-organ coverage to capture physiological motion in its entirety. From cardiac motion to joint movement, complete anatomical regions can be imaged simultaneously with exceptional clarity, minimizing temporal mismatch and advancing CT from partial coverage to whole-organ synchronized imaging.

CardioCapture 2.0 achieves an effective temporal resolution of 8 ms through AI-powered cardiac motion correction. By precisely segmenting cardiac structures, tracking motion trajectories, and generating multi-phase motion fields, it enables synchronized motion correction of the coronary arteries, valves, myocardium, and ventricles for clearer visualization of cardiac dynamics throughout the entire cardiac cycle.

CardioCapture 2.0 reconstructs multi-phase images before and after the target phase, using deep learning networks to accurately extract coronary centerlines and establish inter-phase motion models. This enables precise motion correction of segmented coronary images for clearer coronary visualization.

CardioCapture 2.0 provides synchronized motion correction for the myocardium, valves, and ventricles. Powered by deep learning-based cardiac segmentation, it extracts comprehensive cardiac information, effectively suppresses motion artifacts, and significantly enhances structural clarity and diagnostic confidence.

The Ultrix™ detector features high-precision dicing for 0.33 mm pixel size at isocenter. A reduced reflector thickness enables an expanded active detecting area, improving photon collection efficiency for low-noise, high-resolution imaging. This supports image quality in low-dose and large-patient examinations.

The Ultrix™ detector integrates a 3D-printed thin-wall anti-scatter grid (ASG) with one-to-one alignment between grid cells and scintillator pixels for effective scatter rejection. Made from a high-density heavy metal alloy, the ASG combines structural rigidity with a thin-wall design, supporting efficient X-ray transmission and photon detection for high SNR and clear image quality.

The uCT SiriuX Ultrix™ features dual liquid-metal-bearing X-ray tubes with a minimum focal spot of 0.4 × 0.5 mm, helping reduce geometric penumbra and support high spatial resolution. Combined with dual Ultrix™ detectors, the X-ray tubes and detectors form an integrated imaging chain for detailed image visualization. Multiple focal spot options provide flexibility for high-resolution imaging and high-throughput scanning.

The Ultrix detector integrates the photodiode sensor array and ADC electronics through through-silicon via (TSV) technology, shortening the analog signal transmission path from centimeters to micrometers. This significantly reduces signal interference and electronic noise, enabling high-SNR, high-fidelity signal acquisition and preserving more valuable signal information for image reconstruction, particularly in low-dose imaging.

uCT SiriuX Ultrix™ features the Artificial-Intelligence Iterative Reconstruction (AIIR) , combining model-based iterative reconstruction (MBIR) with advanced deep learning denoising. By jointly modeling system optics, noise, anatomy, and physical statistics, AIIR effectively suppresses image noise and artifacts while preserving natural image texture and anatomical structures. The result is high-quality imaging at reduced radiation dose across a broad range of clinical applications.

Its 3D deep neural network with attention mechanism enhances critical structures such as plaques, stents, and small vessels, improving edge definition and anatomical clarity while suppressing noise and image degradation at reduced dose. CardioBoost supports high-quality cardiac imaging for coronary stenosis assessment, plaque characterization, and myocardial evaluation.

Enabled by its Twin-Ring Gantry Design, uCT SiriuX Ultrix™ expands the imaging geometry of dual-source spectral CT. Extending the detector geometry along the X–Y plane provides a maximum spectral imaging field of view of 470 mm. This enables spectral imaging across a broad anatomical range, with consistent image quality and quantitative performance.

uCT SiriuX Ultrix™ generates high- and low-energy X-rays independently from two X-ray tubes, while the PureBeam Filter minimizes spectral overlap for clear energy separation at the source. Synchronized acquisition of high- and low-energy data enables precise spectral data matching, while dual 16 cm wide-coverage detectors support 0.33 mm ultra-small-pixel spectral imaging, combining extensive anatomical coverage with exceptional structural detail.
