WeMed Medical Unveils Breakthrough AI-Driven PrecisionCT System For Neurointervention And Beyond
WeMed Medical has announced a major advancement in interventional imaging with its independently developed PrecisionCT system, a next-generation solution based on cone-beam CT (CBCT) and powered by artificial intelligence.
PrecisionCT leverages AI algorithms to reconstruct high-resolution 3D images from 2D rotational data, offering detailed visualization of complex anatomical structures such as nerves and soft tissues. While retaining the real-time dynamic imaging capabilities of digital subtraction angiography (DSA), PrecisionCT delivers CT-level soft tissue contrast-significantly enhancing clinical insight.
At the core of the system is WeMed's proprietary FastAIRecon neural network architecture, which performs end-to-end AI optimization across data acquisition, scatter correction, and 3D reconstruction. The result: a 50% reduction in reconstruction time and industry-leading low-contrast resolution of 0.3%, capable of detecting subtle hemorrhages with density differences as small as 3 HU.
PrecisionCT also supports real-time multimodal registration-including DSA, OCT, IVUS, CT, MRI, and PET-with sub-millimeter accuracy, enabling more comprehensive diagnoses.
Key Advantages
Compared to traditional CT, PrecisionCT offers:
- Higher spatial resolution
- Lower radiation dose
- Robust metal artifact reduction
- Enhanced image quality through AI-powered noise reduction and contrast optimization
- Real-time procedural feedback and planning
During the image reconstruction phase, AI rapidly denoises 512³ matrix data within milliseconds, dramatically improving the signal-to-noise ratio. It also automatically segments tissues, detects tumor characteristics, and generates multi-planar and maximum intensity projection (MIP) views-making complex interventional planning more intuitive than ever.
The system offers automatic 3D reconstruction in both wide-field and narrow-field modes, allowing physicians to instantly select optimal viewing angles. Integrated with DSA feedback mechanisms, it reduces the time needed to identify the best projection angle from minutes to seconds-critical during high-risk procedures.
Precision in Neurointervention
In neurointervention, where accuracy is paramount, PrecisionCT delivers value across all procedural stages:
- Preoperative Planning: Offers a detailed view of lesions to support surgical strategy development.
- Intraoperative Navigation: Provides precise length and angle measurements, with 360° visualization of vascular calcifications-reducing stent malapposition by up to 40% and enabling real-time detection of complications such as thrombosis or vessel rupture.
- Postoperative Assessment: Dual-phase scanning enables clear evaluation of vessel recanalization, stent placement, and tumor embolization, reducing the need for repeat interventions.
A key breakthrough lies in the application of Monte Carlo-based scatter and attenuation correction technologies. By simulating the trajectories of millions of photons, the system effectively eliminates scatter noise and beam hardening artifacts during X-ray transmission, significantly enhancing image clarity and diagnostic reliability.
