Short summary
In the state-of-the-art of static magnetic localization of capsule endoscopes relatively large magnets compared with the small capsules are used. Therefore, small disc magnets and ring magnets for integration with the built-in components were evaluated. The mean position and orientation errors did not exceed 5 mm and 4° for all applied magnets except the thinnest disc magnets with a length of 1.5 and 3 mm. Therefore, the state-of-the-art was outperformed even for smaller magnets.
