Abstract

Hyperthermia treatment procedure (HTP) is an alternative treatment for cancer, where it induces heat and forms the biological effect. The efficiency of hyperthermia procedure depends on the focusing distance position of the electromagnetic energy in order to elevate the temperature of the cancerous tissue within 41oC–45oC at a certain period of time. However, current non-invasive HTP technology had limitations in its penetration depth and focusing distance position toward human tissues. Thus, this research is carried out to minimize the limitations of HTP by investigated the effects of integrations of metamaterials (MTM) lens with HTP. There are four main components are required for development in order to simulate this research project, which are breast phantom, microstrip antenna, MTM lens and water bolus. These components are developed using SEMCAD X software simulator. The breast phantom is designed based on the real characteristics of the breast images, which are obtained from the referred hospital. The simulation is carried out in order to obtain Specific Absorption Rate (SAR), antenna directivity and antenna return loss. From these parameters, the penetration depth and focus position distance capability can be determined towards the treated tissues. As a result, HTP design with the integration of 0.915 GHz microstrip antenna with aluminium single layer MTM metal slab presents the penetration depth up to 76 mm and focus position distance at the of 22 mm to 76 mm. However, when water bolus is integrated the penetration depth is changed to 73 mm, while the focus position distance is in the range of 22 to 73 mm. Therefore, the research objectives are successfully achieved. Nevertheless, further research or work necessitates in order to improve the attainments of focus position distance with different sizes or positions of breast cancer phantom.
