This paper presents a model and the validation of microwave radiation into the surrounding breast tissues, these patterns are obtained by applying ablation therapy.
Electrochemotherapy (ECT) is an application of reversible electroporation currently used in the European clinical practice to enhance absorption of chemotherapeutic drugs successfully used in the treatment of cutaneous and subcutaneous tumors. High response ratings obtained in these tumors encourages further investigation about the application of ECT in deep-seated tumors. As an approach to real anatomical...
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 one of the most common diseases and has high mortality among Mexican women. Thermic therapies are one of the most promising techniques these days. Microwave ablation transmits electromagnetic energy inducing a focalized temperature increment to achieve tumor necrosis in a minimally invasive way. One of the main limitations in the development of thermotherapy percutaneous applicators...
This paper describes the procedure to make a realistic and novel breast and breast cancer phantoms in order to mimic acoustic and geometric properties of the woman breast. Comparing the propagation speed of sound in our phantoms with others papers, we achieved 96.34 % of similarity in breast phantoms and 96.99 % of similarity in breast cancer phantoms by using accessible and cheap materials; furthermore,...
Thermal interstitial microwave ablation comparison between swine breast tissue and breast phantom using a coaxial antenna was presented. Experimental protocol was composed by a radiation system and a thermometry system. Coaxial antenna works at 2.45 GHz, power apply during experiments was 10 watts for 5 minutes. Thermal sensors were placed next to the antenna, at 0.50 cm, 1 cm and 1.50 cm to the antenna...
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...
Most phantom models do not include distinct definitions of tumor and normal tissue. This article proposes a novel solid breast - tumor phantom for microwave hyperthermia in breast cancer treatment. According to tissue dielectric properties reported, we performed phantom. A Network Analyzer and Dielectric Probe Kit measured dielectric constant and electrical conductivity for both breast normal tissue...
