Background:

Tumor ablation planning is complex, requiring surgeons to navigate challenging anatomies.
Suboptimal planning can lead to complications like over- or under-ablation.
Current methods rely heavily on clinician experience, which can be insufficient for multi-objective optimization.

Purpose of the Study:

To develop a novel computational optimization approach for tumor ablation planning.
To create a system that achieves complete tumor coverage with minimal invasiveness.
To reduce the number of ablations, needle trajectories, and damage to healthy tissue.

Main Methods:

Integration of a Genetic Algorithm (GA) into an ablation planning system.
Encoding candidate ablation plans as chromosomes within a constrained search space.
Designing an exponential weight-criterion fitness function to balance multiple objectives.

Main Results:

The proposed system successfully generated optimal solutions for tumor ablation planning.
The Genetic Algorithm effectively handled the multi-objective nature of the problem.
The planner achieved complete tumor coverage while minimizing invasiveness.

Conclusions:

Computer-assisted planning with optimization algorithms can enhance tumor ablation procedures.
The developed system offers a robust method for balancing competing objectives in ablation planning.
This approach promises improved patient outcomes by optimizing treatment strategies.
