AIMD MRI-Compatibility Knowledge Base

Mapping how the AIMD industry passes MRI compatibility — the mechanism-layer base feeding our MR-safety decisions.

Topics

Cross-cutting analyses across the evidence base.

• Hazard-solution-grid
  Which mitigations cover which hazards, at a glance.
• Hazard-solution-detail
  Per-hazard mechanisms, exemplar patents, companies.
• TS 10974:2018 Test Protocols
  Per-hazard test-protocol overview: clause map, shared test rigs, compliance-criteria split, gaps.

Hazards

One complete analysis per MR hazard.

• RF Heating
  RF field heats leads and tissue.
• RF Malfunction
  RF field disrupts device electronics.
• Gradient Heating
  Switching gradients cause eddy-current heating.
• Gradient Vibration
  Gradients vibrate magnetic components.
• Gradient-Induced Stimulation
  Induced voltage triggers unintended stimulation.
• Gradient Malfunction
  Gradients disrupt device operation.
• B₀ Displacement Force
  Static field pulls on magnetic mass.
• B₀ Torque
  Static field twists the implant magnet.
• B₀ Malfunction
  Static field disrupts device function.
• Image Artifact
  Implant distorts the MR image.
• Combined Fields (pending)
  Combined-field effects.
