Engineering Notes
Vendor-specific. Used by radiologists and AI tools to identify reconstruction algorithm (e.g., soft tissue vs bone kernel). Critical for AI model inputs — same anatomy reconstructed with different kernels behaves differently.
Troubleshooting
AI CAD systems with unexpected miss rates may be kernel-sensitive. Audit Convolution Kernel values across sites when validating algorithm performance.
