1. A method of determining a temperature and facilitating ablation of tissue of a subject, comprising:

  • positioning a catheter of an ablation system at a target anatomical location of a subject;

    wherein an integrated catheter tip is positioned along a distal end of the catheter, the integrated catheter tip comprising a radiofrequency electrode, a radiometer and a temperature-measurement device,wherein the ablation system further comprises a generator for providing energy to the radiofrequency electrode; and

    wherein the ablation system further comprises a non-transitory computer-readable medium and a processor;

    determining a temperature of a tissue of the subject at a depth relative to a surface of the tissue based on, at least in part, a signal generated by the radiometer, a signal generated by the temperature-measurement device and operation parameters for the radiometer and the temperature-measurement device stored on the computer-readable medium;

    delivering radiofrequency energy to the tissue of the subject by activating the generator to provide power to the radiofrequency electrode; and

    automatically regulating operation of the radiofrequency electrode based, at least in part, on the determined temperature.
