HEAT: High-Efficiency Simulation for Thermal Ablation Therapy

GPU-accelerated real-time thermal ablation simulation published in IJCARS 2025

Abstract

Percutaneous thermal ablation is increasingly popular but still suffers from a complex preoperative planning, especially regarding the prediction of the ablation zone. We propose HEAT (High-Efficiency simulation for thermal Ablation Therapy), a novel GPU-accelerated simulation framework for thermal ablation that enables real-time planning.

This work was published in the International Journal of Computer Assisted Radiology and Surgery (IJCARS) in 2025.

Motivation

Thermal ablation is a minimally invasive cancer treatment that uses heat to destroy tumors. However, accurately predicting the ablation zone (the area that will be destroyed) remains challenging. Traditional simulation methods are too slow for clinical use, taking minutes or even hours to compute.

Approach

HEAT leverages GPU acceleration to achieve real-time performance:

  • Fast computation: Results in under 1 second for interactive planning
  • GPU parallelization: Efficient handling of 3D volumetric data
  • Physical accuracy: Implements realistic heat transfer models including:
    • Pennes bioheat equation
    • Perfusion effects
    • Heat sink effects near blood vessels

Results

The system demonstrates:

  • Real-time performance: Sub-second simulation times
  • Clinical accuracy: Validated against experimental data
  • Practical utility: Integrates with existing surgical planning workflows
