Wireless Capsule Endoscopy (WCE) is a non-invasive technique used to visualize the digestive system in the human body. Many gastrointestinal (GI) system diseases such as Crohn's disease, tumor, bleeding, and polyps can be easily diagnosed with WCE. In recent years, the tendency to WCE method has been increasing especially in order to eliminate the disadvantages of traditional colonoscopy (being painful, risk of infection, completely dependent on operator skill, psychologically disturbing the patient). Here, together with the diagnosis made with the WCE technique, determiningthe location of the disease detected in the intestine is of great importance for the medical specialist. Therefore, this study focused on determining the position of WCE in the intestine. In this study, a cube-shaped magnet was used together with the wireless capsule, and the predicted positions of the wireless capsule in the small intestine were obtained using magnetic sensors placed on the human body model and the LM-ABC optimization algorithms.As a result, 5D (3D position, 2D orientation) localization procedure was performed with the analytical magnetic model of the cube magnet.
