Catheter curvature affects accuracy of intraventricular
blood volume measurement when using
conductance catheter techniques, especially with irregular
geometries, such as in the right ventricle. To investigate this
effect, we present results from using different curved catheter
configurations and different numbers of electrodes in a simple
Finite Element model. It was found that there is an apparent
increase in accuracy with curvature, due to greater linearity in
the field in the region of the measurement electrodes, which are
located farther from the source electrodes as curvature
increases. Also, optimization using Genetic Algorithms is
presented as a method to find the optimal distribution of
measurement electrodes. We plan to extend these results to
develop improved electrode configurations for using in blood
volume measurement in the right ventricle.
