AI-Enhanced Angiography Systems for Precision Interventional Oncology

The Artis genio and Artis icono series represent a shift in interventional radiology by utilizing artificial intelligence to optimize image guidance during tumor embolization. These platforms address the technical complexities of liver cancer treatment and benign prostate hyperplasia by enhancing the digital supply chain of medical imaging data from acquisition to real-time navigation.

Automated Motion Correction in Volumetric Datasets
During the European Congress of Radiology held in Vienna, technical specifications for the Syngo DynaCT MORE software were detailed. A primary challenge in three-dimensional cone beam computed tomography (CBCT) of the thorax and abdomen is image degradation caused by physiological motion, such as respiration or vascular pulsation.

The system utilizes iterative image reconstruction algorithms to achieve automated motion correction. By realigning high-contrast structures — specifically vessels and interventional devices—the software restores datasets that would otherwise be unusable due to blurring. This mechanism provides a stable 3D anatomical foundation, potentially reducing the necessity for repeated X-ray scans and lowering the cumulative radiation exposure for the patient.


Algorithmic Planning and Vascular Mapping
To manage the high dimensionality of vascular structures, the myEmbolization Guide employs organ-specific algorithms trained for liver and prostate workflows. This software automates the contouring of tumors, providing a three-dimensional depiction of the target lesion and a defined treatment zone.

The technical utility of these systems lies in their ability to differentiate feeder vessels from non-feeder vessels through comprehensive vascular mapping. For interventional radiologists, this precision is critical during prostatic artery embolization or liver chemoembolization, where inaccurate catheter placement can lead to off-target complications. The integration of these tools standardizes the navigation process, supporting clinical decision-making in environments with varying levels of staff experience.


Real-Time Denoising via the Optiq AI Imaging Chain
The hardware is supported by the Optiq AI imaging chain, which focuses on maintaining image fidelity while managing radiation dose. During the image-processing phase, an AI-based algorithm identifies and filters noise generated by X-ray scatter and electronic system interference.

This denoising process occurs in real time across two-dimensional imaging modes. By computationally compensating for scatter effects, the system achieves higher contrast-to-noise ratios at the same dose levels used in conventional angiography. This technical refinement is essential for visualizing micro-catheters and embolic agents in deep-seated abdominal targets.

Impact on Clinical Workflow and Standardization
The Artis portfolio includes a redesigned user interface intended to synchronize operations between the control room and the examination room. According to Prof. Dr. med. Frank K. Wacker, president of DeGIR, workflow guidance and standardization are instrumental in reducing procedural errors and improving the training trajectory for medical residents. By automating manual planning tasks, the platforms allow for a more personalized approach to therapy, even as patient volumes increase relative to available specialized medical personnel.
