Product description
The new‑generation 瑞鈊™ magnetic tracking sensor system uses micro‑magnetic field technology to overcome occlusion issues of optical tracking and the size and EMI susceptibility of conventional electromagnetic systems. Designed for percutaneous and endovascular interventions, guidewire and catheter tracking, and other image‑guided procedures in clinical and research environments.

Innovative technology

• Metal‑tolerant tracking: stable pose capture and positioning accuracy in metal environments.
• Electromagnetic resilience: robust performance across complex EM scenarios.
  
  • Facilitates efficient compliance with medical device EMC testing.
• Weak‑field operation: advanced nonlinear calibration for low‑signal accuracy.
  
  • Minimizes interference to surrounding equipment.
• Compact form factor: small magnetic field generator and compact sensors for easy integration.
  
  • Embedded sensors simplify device integration.
• Plug‑and‑play: sensors can be used without per‑case recalibration.
  
  • Reduces setup time and streamlines workflow.
• Scalable tracking: expandable architecture supports multi‑sensor, unlimited tracking configurations.
  
  • Pure digital signals provide additional immunity to EM coupling.
