摘要：
Ablation systems and methods detect and address distortion caused by a variety of factors. A method includes measuring a temperature curve at target tissue； applying ablation energy to the target tissue； determining a peak temperature on the temperature curve； if the peak temperature is greater than the predetermined peak temperature, determining a time at which the temperature curve crosses to a lower temperature； and if the determined time is greater than a predetermined time, generating a message indicating that the target tissue was successfully ablated. Another method includes determining a distance between a remote temperature probe and an ablation probe, applying ablation energy to target tissue, measuring temperature at the remote temperature probe, estimating ablation size based on the determined distance and the temperature measured by the remote temperature probe, and determining whether the target tissue is successfully ablated based on the estimated ablation size.
