1. A system for performing a medical procedure with at least one instrument on a patient comprising:

  • an imaging head defining a field of view relative to the patient, the imaging head including;

    at least one radio-frequency transmitter that emits a least one signal in the field of view;

    at least one radio-frequency receiver that receives a plurality of reflected radio frequency signals based on at least one electrical property of at least one material in the field of view and the at least one instrument;

    a workstation having a control module that determines, based on the plurality of reflected radio frequency signals received by the at least one radio-frequency receiver, a location of at least one boundary of the at least one material within the field of view and a location of the at least one instrument in relation to the patient in the field of view;

    wherein the workstation is configured to determine a type of material associated with the at least one instrument based upon the reflected radio frequency signals associated with the at least one instrument and a signal produced by the at least one radio-frequency transmitter; and

    a display that displays an image of the location of the at least one boundary, and renders an icon of the at least one instrument on the image.
