Modern colonoscopy systems depend on continuous, high-resolution video to support accurate diagnosis. As image resolution increases, clinicians and systems must handle larger volumes of visual data in real time. Small polyps, subtle tissue variations, or brief visual cues can be difficult to identify consistently during live procedures, especially as procedure duration increases.
To improve detection reliability, colonoscopy platforms increasingly integrate AI-based video analytics. These systems analyse live video and highlight regions that require closer inspection. However, AI accuracy depends as much on video quality, latency, and consistency as it does on the algorithm itself. The iWave 12G SDI 8K/4K Frame Grabber addresses this requirement by providing a direct, high-performance interface between colonoscopy imaging systems and GPU-based AI platforms.
High-Quality Video Capture for AI-Assisted Colonoscopy
AI-based polyp segmentation relies on fine visual detail. Compression can remove or distort subtle features such as texture, colour transitions, and boundary edges, reducing inference accuracy. The iWave 12G SDI Frame Grabber captures uncompressed, high-resolution SDI video, ensuring that AI models receive data that closely represents the original clinical scene.
The frame grabber supports 4K video at up to 60 fps and 8K video at up to 30 fps, meeting the performance requirements of advanced medical imaging systems that demand both high resolution and deterministic behaviour.
Key capabilities include:
- 12G SDI input and output for professional medical video equipment
- Uncompressed video capture for AI-ready image quality
- PCIe Gen3 interface for high-bandwidth, low-latency data transfer
- Standards-compliant SDI support for straightforward system integration
Video Capture Architecture for AI-Assisted Colonoscopy
Most colonoscopy camera systems used in clinical environments are based on SDI video interfaces because SDI delivers stable, deterministic, and uncompressed video. The iWave 12G SDI Frame Grabber integrates directly with these SDI-based camera systems, avoiding protocol conversion and reducing system complexity.
After capture, video data moves over PCIe to GPU-based AI platforms, where segmentation models process frames in real time. This architecture supports low latency and consistent frame delivery, both of which are essential for live AI assistance during colonoscopy procedures. By combining native SDI support, uncompressed video capture, and high-bandwidth PCIe connectivity, the frame grabber provides a practical foundation for AI-enabled colonoscopy systems.
How iWave Frame Grabber Interacts with NVIDIA Platforms
The iWave Frame Grabber integrates with NVIDIA platforms using GPUDirect, enabling direct data transfer from the frame grabber to GPU memory over PCIe. This approach avoids unnecessary CPU involvement, reduces system overhead, and improves end-to-end latency.
GPUDirect support allows efficient integration with NVIDIA frameworks such as DeepStream and Holoscan, where video streams can be processed for real-time analytics and AI inferencing. This capability is particularly important in medical applications, where predictable latency and sustained throughput are required for imaging, diagnostics, and real-time clinical decision support.
Enabling AI-Ready Colonoscopy
As colonoscopy systems evolve toward real-time AI assistance, reliable video capture and efficient data movement become core system requirements. The iWave 12G SDI 8K/4K Frame Grabber delivers high-quality SDI video directly to GPU-based AI platforms over PCIe, supporting scalable and future-ready system designs.
By combining medical-standard SDI interfaces, uncompressed video delivery, and efficient GPU integration, the frame grabber enables practical deployment of AI-based polyp segmentation in live colonoscopy workflows—supporting clearer visualisation, faster interpretation, and more confident clinical decisions.
