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

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)

	PRD	r	R-square	∆PRD	∆r	∆R-square

Type 2-processed	0.5057	0.8880	0.7442	48.15%↓	24.08%↑	1426.08%↑
Type 3	1.3657	0.5904	0.8650	80.16%↓	63.23%↑	7.12%↑
Type 3-processed	0.2709	0.9637	0.9266	80.16%↓	63.23%↑	7.12%↑
Type 4	1.3240	0.6043	0.7531	73.28%↓	53.44%↑	12.12%↑
Type 4-processed	0.3945	0.9273	0.8444	73.28%↓	53.44%↑	12.12%↑

The ∆ values correspond to percentage changes comparing the data with and without wavelet processing
