Abstract
System and methods for monitoring cardiac ablation procedures are disclosed. The system can comprise an imaging device and an image processor. The imaging device can be configured to acquire successive frames and radio frequency signal data of a heart. The image process, coupled to the imaging device, can be configured to obtain a signal envelope of the radio frequency signal data, generate a strain map based on the signal envelope, apply a strain threshold to the strain map for classification of lesion tissue, and provide an image which visualizes lesion formation during the cardiac ablation procedures in real-time.
