Electrical capacitance volume sensors, tessellated electrodes, and segmented electrodes for capacitance volume sensing

A system for generating a three-dimensional image of a vessel interior or other object or for sensing the contents of a vessel interior, volume or other object, the system comprising:

• a sensor comprising a plurality of electrodes or plates where the electrodes or plates are tessellated on a surface of a sphere such that all electrode or plate shapes are identical and each vertex of plates touches the same number of plates as all other vertices, wherein the sensor is adapted to provide electric field distribution and sensor sensitivity in three geometric dimensions;
• and
• a processing system, the processing system programmed with instructions for executing on the processing system to calculate material volume inside the sensor from information collected by the sensor.

• and
• a processing system, the processing system programmed with instructions for executing on the processing system to calculate material volume inside the sensor from information collected by the sensor.

A system for generating a three-dimensional image of a vessel interior or other object or for sensing the contents of a vessel interior, volume or other object, the system comprising:

• a sensor comprising a plurality of electrodes or plates where the electrodes or plates are segmented into smaller sub-plates or segments wherein the sub-plates or segments are each designated as excitation or ground, wherein the sub-plates or segments are activated with different voltage excitations or ground to distribute a charge accumulation across the plates, wherein the sensor is adapted to provide electric field distribution and sensor sensitivity in three geometric dimensions;
• and
• a processing system, the processing system programmed with instructions for executing on the processing system to calculate volume of material inside the sensor from information collected by the sensor.
