2、nt procedures for diagnosing a variety of heart rhythm disturbances.The magnetic navigation system utilizes low-intensity magnetic fields to triangulate the probe tips position inside the human body.These magnetic fields can disturb the signal coming from the positioning coils and cause erroneous re

3、sults.Any cable or connector from the catheter tip to the system needs to be well-shielded against external fields to ensure the accuracy of the medical procedure.A magnetic field simulation model has been developed to design effective shielding for the connector used in the application.To validate

4、the performance of the shielding design,a magnetic shielding effectiveness measurement system is built.This measurement method directly assesses the magnetic field inside and outside of the connector enclosure to generate three-dimensional(3D)plots of the magnetic field intensity.The results allow u
