This study developed and tested inductive loop antennas for hyperthermia treatment. The simple loop applicators demonstrated efficient peripheral heating for tumors at a depth of 2-3.5 cm.
Area of Science:
- Medical Physics
- Biomedical Engineering
- Electromagnetics
Background:
- Deep heating remains a key research area in hyperthermia treatment.
- Developing effective heating applicators is crucial for therapeutic outcomes.
Purpose of the Study:
- To design, develop, and analyze a simple loop antenna as a heating applicator for hyperthermia.
- To evaluate the performance of inductive loop antennas for targeted tissue heating.
Main Methods:
- Two inductive loop antennas (7 cm and 9 cm radii) were designed, simulated, and constructed for 27 MHz operation.
- Theoretical analysis employed Green's and Bessel's functions.
- Experimental validation was conducted using phantom models radiated by the antennas.
Main Results:
- Specific absorption rate (SAR) distributions were correlated with phantom temperature measurements.
- Theoretical, simulation, and experimental results showed good agreement.
- Achieved penetration depth was measured to be between 2-3.5 cm.
Conclusions:
- Inductive current loops are effective applicators for peripheral hyperthermia.
- The developed loop antennas are suitable for treating spherical tumor formations at depths of 2-3.5 cm.
