Table 1 PRD, r and R-square values for comparison between the simulation signals with simulated interference (type 1, type 2, type 3 and type 4) and with reduced simulated interferences (type 1-processed, type 2-processed, type 3-processed, type 4-processed)

From: An on-line processing strategy for head movement interferences removal of dynamic brain electrical impedance tomography based on wavelet decomposition
