    A low-parametric reconstruction method for human bladder volume estimation has been developed and compared to the conventional image-based global impedance method. Main advantages of the new method are conductivity invariant volume estimate and increased accuracy for medium to high bladder volumes.

    The objective of impedance-cystovolumetry is the continuous, non-invasive monitoring of bladder volume. By using electrical impedance tomography, a correlation between the change of impedance in the image and bladder volume can be found. However, the typically used timedifferential approach has the problem of both requiring a calibration measurement with an empty bladder and being dependent on the urine conductivity. This paper presents an improvement to the time-differential approach using multifrequency electrical impedance tomography.
