Summary
Microwave tomography accurately monitored phantom heating experiments. The HeatSYNC gel, designed to enhance thermal ablation, successfully altered microwave ablation heating patterns as intended.
Area of Science:
- Medical Physics
- Biomedical Engineering
- Electromagnetic Imaging
Background:
- Microwave ablation is a minimally invasive technique for tumor treatment.
- Controlling and visualizing heat distribution during ablation is crucial for efficacy and safety.
- Novel materials like HeatSYNC gel aim to improve ablation performance.
Purpose of the Study:
- To experimentally validate microwave tomography for monitoring phantom heating during microwave ablation.
- To investigate the impact of HeatSYNC gel placement on microwave ablation heating patterns.
Main Methods:
- Phantom heating experiments were conducted using microwave ablation.
- Temperature was monitored in real-time using microwave tomography.
- Heating patterns were compared with and without HeatSYNC gel positioned near the ablation device.
- A discrete dipole approximation-based algorithm was used for image reconstruction.
Main Results:
- Microwave tomography successfully recovered accurate property distributions correlating with temperature rises.
- Observed changes in heating patterns confirmed the HeatSYNC gel's effect when placed near the antenna.
- Results aligned with prior simulation studies.
Conclusions:
- Microwave imaging is effective for monitoring ablation-induced heating patterns.
- HeatSYNC gel demonstrably modifies heating distribution, enhancing ablation potential.
- These findings support the use of HeatSYNC gel for tailored thermal ablation of tumors.
