Classification of positioning methods with image processing and body modeling with SEMCAD

In the human body, there are organs with various tissues and different properties, which causes asymmetric signal propagation and central frequency shift. Power absorption in the human body varies with the characteristics of each tissue in the body. The channel of the human body affects the accuracy of these methods by creating fading and multi-paths. In fact, the accurate positioning of capsules in the digestive tract of the human body and achieving tracking accuracy of a few millimeters in an environment with high loss and having a variable release channel is one of the existing challenges. Therefore, a proper path loss model is required to have an accurate positioning. Therefore, according to the importance of modeling the human body channel, the methods proposed in the modeling of the human body are first examined, and in this article, software modeling of the body and introduction of various positioning methods are done.
