There is provided a system (100) for measuring impedance at multiple locations within a body of a patient, comprising: an elongated probe sized and shaped for being disposed within a cavity of the body of the patient or in an extracorporeal position, at least one pair of parallel transmission wires (112) disposed along a length of the elongated probe, a plurality of impedance elements (116), each connected to the at least one pair of parallel transmission wires at a respective spaced apart location along the length of the elongated probe in a ladder arrangement, a transmitter configured for injecting an electrical signal to the at least one pair of parallel transmission wires (112), a receiver configured for measuring a plurality of reflections of the electrical signal from the plurality of impedance elements, and a processor configured for computing an impedance value for each of the impedance elements according to the measured plurality of reflections.
