Abstract :
A system for the electrical impedance tomography is described in the paper. A digital signal processing (DSP) chip is used to control the operation of every module. As DSP is easy for high-speed control and flexible for embed algorithm and data preprocessing, the system can sample the data and reconstruct the impedance variation distribution quickly that makes the real time image monitoring possible. At here, the principle, implementation and performance of the system are illustrated. And the experimental result, the reconstructed impedance variation distribution image, shows the efficiency of the system.
