摘要：
Illustrative embodiments provide systems and methods for radiometricallymeasuringtemperature and detecting tissue contact during ablation. An interface moduleincludes a firstinput/output (I/O) port for receiving radiometer and thermocouple signals froman integratedcatheter tip (ICT) that includes a radiometer a second I/O port for receivingablative energyfrom an electrosurgical generator a temperature display a patient relay acomputer-readablemedium storing radiometer and thermocouple parameters and instructions forcausing theprocessor to: calculate a temperature adjacent to the ICT based on theradiometer andthermocouple signals and the parameters causing the temperature display todisplay thecalculated temperature closing the patient relay to pass ablative energy fromthe second to thefirst I/O port determining whether the ICT is in contact with tissue based onthe radiometersignal. An output device indicates whether the ICT is determined to be incontact with thetissue.
