Case Study of conductance changes during the transition of hydrocephalus using our prototype design in simulations using finite element analysis. The sizes of the intermediate stages B-D (not shown) were artificially created by interpolation to emulate transitions from normal to hydrocephalus. The projections of volume changes were taken as size changes of the lateral ventricle with known volumes of the normal and hydrocephalic lateral ventricle. The simulations were repeated five times with different sensor positions located between 1 – 5 mm away from the central axis. An 8 fold increase from normal size correlates with our experimental and simulated analysis.
