Abstract
A method of generating a representation of an active heating zone on a display in real time during an ablation procedure includes processing imaging data of a surgical site generated by an imaging device, navigating an ablation device in proximity to target tissue, delivering electrosurgical energy to the target tissue via the ablation device to generate an active heating zone, detecting a Doppler shift in the imaging data based on the delivery of electrosurgical energy to the target tissue, and generating a representation of the active heating zone relative to the surgical site based on the detected Doppler shift.
Claims20
A method of generating a representation of an active heating zone on a display in real time during an ablation procedure, the method comprising:
- processing imaging data of a surgical site generated by an imaging device;
- navigating an ablation device in proximity to target tissue within the surgical site;
- delivering electrosurgical energy to the target tissue via the ablation device to generate an active heating zone;
- detecting a Doppler shift in the imaging data based on the delivery of electrosurgical energy to the target tissue;
- and
- generating a representation of the active heating zone relative to the surgical site based on the detected Doppler shift.
A system for generating a representation of an active heating zone on a display in real time during an ablation procedure, the system comprising:
- a display;
- an ultrasound probe configured to generate imaging data of a surgical site;
- an electrosurgical generator configured to supply electrosurgical energy;
- an ablation device coupled to the electrosurgical generator and configured to deliver electrosurgical energy to target tissue within the surgical site;
- and
- a processing unit coupled to the display and configured to process imaging data generated by the ultrasound probe to detect a Doppler shift in the imaging data, the Doppler shift based on the delivery of electrosurgical energy to the target tissue,
- wherein the processing unit generates a representation of an active heating zone on the display overlaid on an image of the surgical site based on the detected Doppler shift, the representation of the active heating zone based on the delivery of electrosurgical energy to the target tissue via the ablation device.
