Influence of colour scales on functional electrical impedance tomography images. Examples of minute images in cranio-caudal direction (L1 to L6) (patient 1) with different colour scale endpoints: (a) automatically adjusted colour scales (assigning white to the maximum impedance change), (b, c) user-defined adjusted colour scales. Massive pleural effusion could be excluded. Images are 32 × 32 pixel coloured matrix (white: positive/highest ∆Z; blue: medium ∆Z; black: no impedance change; purple: negative ∆Z, inverted signal).
