Electromagnetic thermotherapy for deep organ ablation by using a needle array under a synchronized-coil system

Area of Science:

• Oncology
• Biomedical Engineering
• Medical Physics

Background:

• Electromagnetic thermotherapy (EMT) is a promising cancer treatment modality with minimal side effects.
• Current EMT systems use high-frequency alternating electromagnetic fields to heat inserted needles for tumor ablation.
• Investigated for various internal medicine and surgical applications.

Purpose of the Study:

• To demonstrate a novel synchronized-coil EMT system for enhanced needle heating.
• To evaluate the efficacy of the new system in vitro and in vivo animal models.
• To assess its potential for minimally invasive cancer treatment.

Main Methods:

• Development of a synchronized-coil EMT system with two synchronized coils and magnetic field generators.
• Exploration of needle heating effects at the center of the coils.
• In vitro and in vivo experiments using a two-section needle array with the synchronized-coil EMT system.

Main Results:

• The synchronized-coil EMT system effectively heats inserted needles.
• The two-section needle array combined with the system demonstrated promising results.
• Experimental data supports the system's potential for effective thermotherapy.

Conclusions:

• The developed synchronized-coil EMT system shows potential for minimally invasive cancer treatment.
• The system may offer superior performance in thermotherapy applications.
• Further research is warranted to optimize and translate this technology for clinical use.
