RADIOFREQUENCY ABLATION WITH PHASE SENSITIVE POWER DETECTION

摘要

2106409 9308756 PCTABS00021 Systems for ablating tissue control radiofrequency power to an ablation electrode (16) by relying upon actual phase sensitive power measurements (72), unaffected by phase shifts between radiofrequency voltage and current. The systems also detect these phase differences (70), if they develop and integrate this factor (30) in making their control decisions.
