Abstract :
The paper presents an algorithm for localization of endoscopic capsules inside the human body. The goal is to determine the position of capsules by measuring the power of received electromagnetic signal on the human skin taking into account losses within the body. The algorithm was first developed and simulated in MATLAB. Simulation results prove its high accuracy and indicate the optimal antenna configuration. Then a C model was generated and modified to comply with standards of system-level modeling languages. Catapult C tool was used for system-level synthesis and generation of a RTL hardware model. Low power dissipation and small hardware area were achieved by ASIC implementation in a 130 nm bulk CMOS technology.
