Invisible Details, Instinctively Revealed by Intelligence


CT imaging has significantly enhanced diagnostic accuracy, yet challenges remain in achieving optimal image quality for complex cases and specialized patient populations. As the AI field evolves, deep learning is driving advancements in CT imaging by improving spatial resolution and contrast while suppressing artifacts. These innovations refine CT capabilities, making the invisible visible and ultimately improving patient outcomes.

AIIR*- AI Iterative Reconstruction

Combining MBIR with deep learning leverages each method's strengths while mitigating their limitations. In AIIR, the data-fidelity term integrates system optics, detector response, and quantum noise models for each scan, preserving detailed anatomical and pathological information from raw projections. While MBIR's high regularization strength can lead to unnatural appearances—especially at low doses—AIIR replaces it with a CNN(Convolutional neural network)-based model capturing complex clinical features through millions of parameters. Together, the two technologies complement each other, allowing more precise noise differentiation and delivers improved image quality.

Motion Artifacts, Instinctively Suppressed by Intelligence


Motion has long been a challenge in CT imaging, often causing artifacts and reducing image clarity. This is particularly critical in dynamic areas like cardiac imaging and when patients struggle to keep their heads still during scans. Advances in technology, including improved temporal resolution and deep learning algorithms, are helping to address these issues, significantly enhancing image quality and diagnostic accuracy.

Synergy of Superior Rotation Speed and Deep Learning

Addressing motion artifacts requires combining improved temporal resolution with deep learning algorithms. While hardware improvements reduce artifacts, deep learning selects optimal phases and corrects severe motion artifacts beyond hardware's limits. This enables the uCT 868 to "freeze" motion and deliver undistorted images with enhanced coronary clarity.

In CT imaging, high acquisition speed minimizes motion artifacts and reduces radiation exposure. The native temporal resolution, which is determined by the rotation speed, directly impacts the quality of the raw data acquired. Currently, it is considered the most relevant indicator for eliminating motion artifacts in coronary artery imaging.

The native temporal resolution, which is determined by the rotation speed, directly impacts the quality of the raw data acquired. Currently, it is considered the most relevant indicator for eliminating motion artifacts in coronary artery imaging.

CardioXphase: Finding the Optimal Phase for Coronary Arteries, Rather Than the Heart

Conventional methods prioritize minimal heart motion but may not correspond to the phase that provides the best image quality for coronary arteries. Instead of using just CT value, CardioXphase leverages AI to accurately extract arteries, focusing on shape regularity and edge sharpness to select the best phase for imaging, enhancing further analysis.

Different cardiac cycles have different optimal phases.
For CT systems with the detector coverage less than 16cm, data acquisition of the whole heart requires multiple cardiac cycles. This implies that each cardiac cycle will have a corresponding optimal phase, especially in the case of irregular heart rhythms. CardioXphase chooses the optimal phase independently from each cardiac cycle, improving the overall coronary artery image quality.

Motion Freeze: AI–Powered Head Motion Artifact Elimination for Clearer Brain Structures

Motion Freeze effectively suppresses head motion artifacts, providing a clear view of brain structures without obscuring lesions. By minimizing the need for repeated scans, it saves time, conserves resources, and avoids unnecessary radiation exposure for patients.

Patient head movement typically involves multiple motion patterns, and no current algorithm can effectively eliminate the resulting artifacts. To establish a gold-standard dataset, the Motion Freeze algorithm simulates artifacts in the X, Y, and Z directions, including rotation, translation, oscillation, and mixed scenarios. By introducing diverse motion artifacts, this approach enables the trained network model to handle a broad spectrum of motion conditions.
