Guiding Control by Magnetic Guiding Device for Capsule Endoscope

The purpose of this paper is quantitative evaluation of guiding control by magnetic guiding device for capsule endoscope (CE). In this report, the magnetic force for a CE manipulating a magnetic guiding device is calculated using a transient response analysis with a finite element analysis software. It was found that the maximum value of magnetic force is defined by the distance between the CE and the magnetic guide device. This paper proposes an approximation for the maximum value as a function of the distance if the distance is between 0.06 m and 0.12 m. From experimental results, the guide control by magnetic guide device is successfully confirmed at the distance of 100 mm. It is noted that the movement speed of the magnetic guide device should be less than 0.066 m/s.
