Computation of sensitivity map in adaptive electrical capacitance volume tomography based on voltage distribution

Adaptive electrical capacitance tomography can improve the image resolution with more flexible control in sensitivity map which become a new research direction for three dimensional capacitance imaging. However, the conventional computation of sensitivity map is time-consuming, a fast approach based on voltage distribution was proposed to solve this problem. The simulation results show that the sensitivity map obtained by the conventional and fast computation approach are very close while the computation time of the later is 20% of that of the former one.
