1. A system for determining the dimensions and geometry of a native valve annulus for trans-catheter valve implantation, the system comprising:

  • a balloon extending in a longitudinal direction;

    a shaft extending in the longitudinal direction within the balloon;

    a first spline connected to the shaft;

    a second spline connected to the shaft;

    a third spline connected to the shaft;

    a first electrode positioned on the first spline;

    a second electrode positioned on the second spline; and

    a sensing electrode positioned on the third spline;

    wherein the first electrode and the second electrode are configured to produce an electrical field upon application of current to the first electrode and the second electrode, the electrical field being detectable by the sensing electrode; and

    a central ring electrode located on the shaft and configured to serve as a reference electrode to allow measurement of values associated with the electrical field produced by the first and second electrodes.
