System for controlling ablation therapy and visualization

The invention relates to a system for controlling ablation therapy and visualization. The system includes a tissue ablation instrument having one or more deployable stylets and a first electromagnetic sensor; and an ultrasound imaging instrument, which may be configured to generate an ultrasound imaging plane and further has a second electromagnetic sensor. Also included may be an electromagnetic field generator configured to be placed proximate the patient's body and further configured to generate an output indicative of a position of the first electromagnetic sensor and the second electromagnetic sensor relative to each other. Also included is a console in communication with the ablation instrument, the ultrasound imaging instrument, and the electromagnetic field generator, where the console is configured to generate a representative image of the tissue ablation instrument and ablation boundaries or cages oriented relative to the ultrasound imaging plane based on the deployment position of the one or more s
