Ultrasound ablation apparatus and methods of use

An ultrasound ablation and imaging system comprising:

• an ablation unit comprising;
• an instrument body configured to be inserted into a tissue, the instrument body comprising a proximal portion and a distal portion;
• one or more ultrasound transducers coupled to the distal portion of the instrument body, wherein the one or more ultrasound transducers are configured for selectively emitting energy for obtaining one or more ultrasound images of surrounding tissue and/or heating, perturbing, or destroying a target tissue, the one or more transducer arranged to form one or more transducer arrays;
• and
• a monitoring unit comprising;
• one or more sensors, coupled to the distal portion, configured to measure one or more characteristics of the tissue, comprising, target and/or surrounding tissue, wherein the one or more sensors comprise at least one of the one or more ultrasound transducers;
• and
• a processor configured to perform ablation monitoring, wherein the processor is configured to receive and process sensor data of the target tissue and/or surrounding tissue to provide real-time ablation monitoring.
