Fig. 8From: Evaluation of electrical impedance tomography for determination of urinary bladder volume: comparison with standard ultrasound methods in healthy volunteersComparison of the electrode configurations (given as deviation in percent) to the actual bladder volume. All four configurations show comparable accuracy for estimation of BCmax. For estimation of residual urine (RU), 1 × 16 is significantly inferior to the Stripes and Matrix configuration. 2 × 8 shows a similar inferior trend, although not significantBack to article page
