QUALITY ASSURANCE AND DATA COORDINATION FOR ELECTROMAGNETIC TRACKING SYSTEMS

摘要

An electromagnetic ("EM") tracking configuration system employs an EM quality assurance ("EMQA") (30) and EM data coordination ("DC") system (70). For the EMQA system (30), an EM sensor block (40) includes EM sensor(s) (22) positioned and oriented to represent a simulated electromagnetic tracking of interventional tool(s) inserted through electromagnetic sensor block (40) into an anatomical region. As an EM field generator (20) generates an EM field (21) encircling EM sensor(s) (22), an EMQA workstation (50) tests an EM tracking accuracy of an insertion of the interventional tool(s) through the EM sensor block (40) into the anatomical region. For the EMDC system (70), as EM field generator (20) generates EM field (21) encircling a mechanical interaction of EM calibration tool(s) (80) with a grid (120) for guiding interventional tool(s) through gird (120) into an anatomical region, the electromagnetic data coordination workstation (90) establishes a coordination system for electromagnetically tracking an insertion of the interventional tool(s) through grid (120) into the anatomical region.
