Event or Problem Description
Additional information was received.A medtronic representative (rep) was not present during the case.However, supposedly, the site was unable to complete the case with the navigation system, because the system could not see the electromagnetic instruments.Three days later, the rep went on site with their demo head and electromagnetic localization system instruments.The navigable field was roughly 200mm^3 (much smaller than normal), but faster movement was not captured by the system ¿ therefore a very unstable magnetic field.
