Adaptive Kaczmarz method for cardiac activity reconstruction in electrical impedance tomography

An adaptive Kaczmarz method to reconstruct conductivity changes from 2D EIT data is described. The framework to combine the adaptive Kaczmarz method and the adaptive mesh refinement is also outlined in the paper. Reconstructions from data collected on a human chest torso are shown. The results accurately recover the conductivity changes during a cardiac cycle and demonstrate the reconstruction performance of the adaptive Kaczmarz method
