Quality assurance and data linkage of electromagnetic tracking system

摘要

The electromagnetic (EM) tracking configuration system uses an EM quality assurance (EMQA) system 30 and an EM data collaboration (EMDC) system 70. For EMQA system 30, EM sensor block 40 is positioned and oriented to represent simulated electromagnetic tracking of an interventional tool inserted through EM sensor block 40 into an anatomical region. A sensor 22 is included. When the EM field generator 20 generates an EM field 21 that surrounds the EM sensor 22, the EMQA workstation 50 tests the EM tracking accuracy of the insertion of the intervention tool through the EM sensor block 40 into the anatomical region. To do. For the EMDC system 70, the EM field generator 20 generates an EM field 21 that surrounds the mechanical interaction between the grid 120 and the EM calibration tool 80 that guides the intervention tool through the grid 120 into the anatomical region. Sometimes, the EM data collaboration workstation 90 establishes a collaboration system that electromagnetically tracks the insertion of intervention tools through the grid 120 into the anatomical region.
