1. A system for predicting ablation volume of tissue, the system comprising a controller having instructions that, when executed by one or more processors of the controller, cause the controller to:
receive information indicative of temperature of a tissue being ablated via an antenna;
extract one or more features of the temperature of the tissue from the information, the one or more features comprising at least one of an area under a curve of the temperature of the tissue, a maximum temperature of the tissue, a thermal dose of the temperature of the tissue, an initial slope of the temperature of the tissue, or an average temperature rise of the tissue; and
execute an ablation volume prediction algorithm to predict the volume of ablation of the tissue based on the extracted one or more features and a trend line derived from a correlated dataset of ablation volumes associated with the extracted one or more features.
