Fiber-optical sensor system for data to facilitate, plan, localize, monitor, or confirm ablation procedures

An ablation system, comprising:

• an ablation probe;
• a sensing system associated with the ablation probe and comprising:
• at least one temperature sensor configured to generate temperature-related data;
• and
• at least one acoustic sensor configured to generate acoustic data;
• and
• one or more processors configured to:
• determine a temperature profile based on the temperature-related data;
• and
• control at least one of operation, sensing, or positioning of the acoustic sensor based on the temperature profile.

A method of operating an ablation system, comprising:

• obtaining temperature-related data from a plurality of FBG sensors disposed along an optical fiber;
• determining a temperature profile along an ablation probe based on the temperature-related data;
• obtaining acoustic data from a fiber-end sensor disposed at a distal portion of the optical fiber;
• and
• controlling at least one of positioning or operation of the fiber-end sensor based on the temperature profile.

An ablation system, comprising:

• an ablation probe;
• an optical fiber extending along at least a portion of the ablation probe;
• a plurality of fiber Bragg grating (FBG) sensors disposed along the optical fiber and configured to generate temperature-related data;
• a fiber-end sensor disposed at a distal portion of the optical fiber and configured to sense acoustic signals;
• and
• one or more processors configured to:
• determine a temperature profile along the ablation probe based on the temperature-related data from the plurality of FBG sensors, and
• control at least one of positioning or operation of the fiber-end sensor based on the temperature profile.
