1. A method for producing capacitive images of a sensing region of a sensor electrode, said sensor electrode comprising a plurality of connection sections and a non-connection section, wherein said sensor electrode is connected to sensor circuitry at a plurality of connection locations located in said plurality of connection sections and not said non-connection section, said method comprising:

  • transmitting a transmitter signal into said sensor electrode at a connection location of said plurality of connection locations;

    receiving a plurality of resulting signals from said sensor electrode at multiple connection locations of said plurality of connection locations, wherein said plurality of resulting signals includes effects of said transmitter signal propagating through said sensor electrode to said multiple connection locations; and

    producing a capacitive image using said plurality of resulting signals, said capacitive image comprising a non-connection value associated with said non-connection section.
