摘要： In planning an ablation procedure, a planned target volume (PTV) is imported, which is typically selected by a doctor but may be computer-identified. An ablation solution comprising a plurality of ablation volumes is generated or selected using a lookup table. Ablations sharing a common axis along a line of insertion are grouped into blocks. Alternatively, the PTV is enveloped in a sphere, and a pre-computed ablation solution (e.g., a 6- or 14-sphere solution) is identified to cover the PTV sphere. Optionally, a mathematical algorithm is executed to increase an axis through the ablation spheres to generate ellipsoidal ablation volumes that envelop the PTV.
