Abstract

Hyperthermia therapy aims to elevate the tumor’s temperature to a therapeutic level without harming healthy tissue nearby. This study found that Metamaterial can augment conventional hyperthermia treatment.
A full segmentation for the human Neck was implemented using the 3D Slicer platform. We built PTGM based on 2D CT gained from the thyroid cancer patient. These images comprise the information necessary for recognizing the six main parts of the Neck model.
In order to develop simulated results for enhanced hyperthermia thyroid cancer, the CST studio was utilized, and values for the SAR and transient temperature in healthy tissue and the tumor were reported in the result.
These methods revealed the following results:
1. Using the MTM results in a SAR of 2.30 W/kg in the tumor area, compared to 1.28 W/kg without MTM.
2. Without MTM present around cancer, the temperature inside 1st cancer is 40.3 ˚C, 2nd cancer is 39.7 ˚C and outside cancer is 37.95˚C.
3. When using MTM, the temperature inside 1st cancer reaches a value of 43.3 ˚C, 2nd cancer reaches a value of 42.7 ˚C, while normal tissue remains at 38.45 ˚C.
5.2. Conclusion and Recommendations
from the results of this study, conclude that:
1. According to SAR calculation, we have a better MWI at 2.4 GHZ frequency.
2. We have better SAR results in the tumor region when using MTM.
3. Without MTM present around cancer, there is a minimal temperature increase in cancer that would cause any damage to the cells.
4. When using MTM, the temperature of cancer reaches a value significant for hyperthermia treatment (greater than 42 ˚C).
5. We have better temperature results in the tumor region when using MTM.
6. Our findings spotted the light on using metamaterial. As SAR shows good efficacy compared to the model without using metamaterial.
7. Our study highlights the importance of using metamaterial to enhance the hyperthermia treatment in thyroid cancer model.
Future Work
An important component of future research is to apply different types of MTM to the implemented system. Also, we desire to apply the same system to different organs to investigate the effect of different dielectric properties of human organs.
