Abstract
A system for magnetic field direction detection when placing a catheter is disclosed, including a sensor configured to track a medical device, the sensor including a magnetic sensor printed circuit board including a plurality of magnetometers arranged in a magnetometer array. The system can include a console coupled to the sensor, including a processor and non-transitory computer-readable medium having stored a plurality of logic modules that when executed by the processor, are configured to perform operations including receiving detected magnetic field strength values detected by the plurality of magnetometers, determining a position on the sensor of each of the plurality of magnetometers, determining the magnetic field source direction based on the detected magnetic field strength values and the position on the sensor of each of the plurality of magnetometers, and displaying the magnetic field source direction on the display.
