For both the numerical and physical phantom studies, the proposed technique with adaptive body model enhances localization accuracy by roughly 30%.ĭiagnosis of the gastrointestinal tract can now be performed with the use of capsule endoscopes, which provide doctors with a lot of valuable information. As a result, the helical antenna, which is smaller than the dipole, was chosen as the signal’s source. The type of transmitting antenna employed in the capsule also has a significant impact on the suggested localization method’s accuracy.

This approach was tested using computer simulations in Remcom XFdtd software using a numerical, heterogeneous human body model, as well as measurements with physical phantom. For each capsule position, this technique uses adaptive estimation of human body model permittivity. An enhanced approach of identifying the location of endoscope capsules using a wireless signal phase detection algorithm is presented in this paper. Because the human body is a complex heterogeneous environment that impacts the propagation of wireless signals, determining the distance between the transmitter and the receiver based on the received power level is challenging. This can be carried out by analyzing the parameters of the electromagnetic wave received from the capsule. The capsule’s location enables exact identification of the regions with lesions. Wireless capsule endoscopes take and send photos of the human digestive tract, which are used for medical diagnosis.
