Abstract
The estimation of bladder volume by electrical impedance tomography is a promising technology to provide continuous volume estimates to patients who suffer from impaired bladder volume sensory. To find an optimized electrode arrangement for electrical impedance tomography of the human bladder, seven different electrode arrangements have been analysed using a finite element model. The arrangements under consideration can be assigned to three general groups: ring arrangements, linear arrangements and matrix arrangements. For each arrangement in these three groups, the condition of the Jacobian matrix and the global impedance for several bladder volumes has been calculated and compared using the EIDORS toolkit.
