US 2010/0063496 A1 · RF ABLATION PLANNER

Abstract

In planning an ablation procedure, a planned target volume (PTV) (70, 102) is imported, which is typically selected by a doctor but may be computer identified. An initial set of candidate ablation regions (112) that covers the PTV (40, 70, 102) is computed. Ablation probe trajectories that avoid critical structures (136) are computed to provide surgical 5 options for safe entry points and angles. An optimization component (14) determines a minimum number of ablation regions, which fully covers the PTV (40, 70, 102), and generates locations and orientations for each ablation (108). A tracking system can be given these ablation targets, enabling the surgeon to control the probe more precisely to the desired location.

a graphical user interface that presents an representation of the mass to a user;
and
an optimization component that receives image data related to the mass and determines the ablation regions to cover the mass.

Dependencies are inferred from the claim text.
