A universal ultrasound electromagnetic needle-tip navigation workstation that uses AI to calibrate two unknown transformation matrices in real time, enabling cross-brand empowerment for the 98% "navigation-orphan" ultrasound systems and delivering mm-level 3D needle-tip navigation, multi-modal image fusion, and real-time misalignment warning.

The invention patent "Two-Unknown Transformation-Matrix Derivation" (TW granted, US pending) serves as the backbone, underpinned by two know-hows — needle-shadow segmentation neural network (2025 IEEE IUS leading) and transformation-matrix search algorithm (10^7× speed-up) — forming a First-and-only-in-class universal EM navigation system that empowers the 98% navigation orphans.

Software-Defined Navigation Workstation: the same hardware activates either the K-number (Standard) standalone workstation or the K-number (Brand) brand-specific accessory based on the running software — on-demand multi-machine sharing amortizes cost, and Apps Market avoids repeated clearance — targeting the US$24-billion navigation market.
