Reconstruction of electrical impedance tomography using improved Newton-Raphson algorithm based on wireless distributed system
2014
In the fields such as non-destructive testing and structural health monitoring, Electrical Impedance Tomography (EIT for short) caused concern for people in recent years. This paper introduced the wireless distributed EIT data acquisition system for the advantages of low costing, reliable, accurate and efficient. For this wireless EIT system we have designed the corresponding software which could receive and process data and reconstruct image in one step. On the other hand, based on the existing algorithms this paper proposed the improved Newton-Raphson algorithm to reconstruct image. The experiment result proved that both the system and algorithm was a successful, accurate and optimized for EIT experiment.
