“…Three methods have been introduced for image reconstruction in EChT before, namely Linear Back Projection (LBP) (Yang and Peng, 2003), Filtered Back Projection (FBP) (Yan and Byrne, 1997) and least square methods (Rahmat et al, 2010). However, LBP method is no-linearity with the sensing mechanism used in the electrical charge tomography, thus image reconstruction is focusing only on the sensor location (Machida and Scarlett, 2005;Rahim et al, 2008).…”
