A correction function, derived from an error correction tool, is applied to the position and orientation readings of the sensor coil. The error correction tool comprises a number of electromagnetic sensors arranged in a fixed and known geometric configuration and is placed surrounding the site of the medical procedure. Sensor data is displayed on an imaging system. In addition, a distortion mapping can be done utilizing optical sensors for relative positioning readings along with an electromagnetic tracking system sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System for local error compensation in electromagnetic tracking systems","description":"A system for local metal distortion correction for using an accurate electromagnetic tracking system in a medical environment comprises an electromagnetic field generator monitoring a medical device h","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9733336","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
