Certain embodiments of the present invention provide methods and systems for improved tumor ablation. Certain embodiments include determining a distance between a tumor and at least one of a plurality of landmarks bounding the tumor in at least one acquired image of an area of interest for a patient, obtaining positional data for an ablation instrument, and displaying a position of the ablation instrument with respect to the tumor. Additionally, a position of the ablation instrument may be dynamically displayed on the fluoroscopic image and/or the at least one acquired image during tumor ablation. Furthermore, a location cursor on the fluoroscopic image may be linked with a location cursor on the one or more acquired images. In certain embodiments, a location of a tip of the ablation instrument may be dynamically displayed with respect to a starting location and an ending location of the tumor.
