[Suppression of geomagnetic field interference in the magnet locating system of the micro-magnetic capsule inside the alimentary tract].
A method for the suppression of geomagnetic field interference is here-in introduced. It is designed for use in the magnet locating system of the engineering-based microcapsule inside the alimentary tract. This method marks the geomagnetic field interference levels by getting the static value. Then subtracting the static value from the dynamic value. The results of the experiment show that the method can assess the geomagnetic fi eld interference levels around thelocating waistcoat accurately. And the three-dimensional tracking trajectory shows that the method has greatly improved the accuracy of the capsule location inside the alimentary tract.
