Abstract:
In this paper, a Single-Input-Multiple-Output (SIMO) fuzzy controller is designed to drive an upgraded clinical real-time Magnetic Resonance Imaging (MRI) system to provide steering forces for an aggregation of ferromagnetic microparticles in the human cardiovascular system according to a pre-set pathway. This kind of endovascular navigation is considered as an important procedure of the catheter-based method for medical treatments against diseases such as some particular types of cancers. The validity of the fuzzy controller has been tested by preliminary simulation results.
