In this paper a series of designs of micro coaxial antennas for MWA therapy to be used for the treatment of breast cancer tumors coupled to both breast and tumoral tissue is presented. The designs were modeled and optimized using Finite Element Method (FEM) simulation to ensure the minimal SWR possible value and obtain several parameters of interest such as the antenna's radiation patterns, temperature...
Breast cancer is a mortal disease in the world [1]. The research on this matter is necessary for finding methods to help counteract this disease. Microwaves are used to treat cancer (hyperthermia), to create medical images for diagnose cancer, etc. To treatment to induced superficial hyperthermia are used monopole antennas, microstrip antennas, etc. Monopole antennas are used to create medical images...
An early detection of small breast lesions by mammography screening may facilitate the cancer treatment by minimally or noninvasive techniques. Recently, new therapies than traditional surgery have been explored to satisfy these demands. Additionally ablative treatments have started to become viable alternative methods to treat patients who cannot be treated by surgery. Microwave energy is promising...
This work presents a computerized lesion segmentation technique on breast ultrasound images. There were applied known techniques such as morphological filtering, Watershed transform and average radial derivative function. To evaluate the performance of the proposed method the resulting segmentation contours were compared with 36 breast US images manually delineated by two senior radiologists. Further,...
Currently, physicians test minimally invasive ablation techniques to determine if they will be acceptable substitutes for surgical removal of primary breast tumors. A study of different electromagnetic hyperthermia ablative therapies, including microwave ablation and radiofrequency ablation, are summarized in this paper. We concluded that further studies are necessary to evaluate its future role as...
