Abstract
The present invention provides systems and methods for radiometrically measuring temperature during ablation. An interface module includes a processor; a first input/output (I/O) port configured to receive digital radiometer and thermocouple signals from an integrated catheter tip (ICT) that includes a radiometer; a second I/O port configured to receive ablative energy from an electrosurgical generator; a temperature display; a patient relay in communication with the first and second I/O ports and the processor; and a computer-readable medium storing radiometer and thermocouple operation parameters and instructions for causing the processor to: calculate a temperature adjacent to the ICT based on the radiometer and thermocouple signals and the operation parameters, causing the temperature display to display the calculated temperature, and closing the patient relay so as to pass ablative energy received on the second I/O port to the first I/O port.
