We report in this work, the generation of a realistic simulation environment to test breast cancer microwave hyperthermia treatment. We introduce firstly a realistic breast phantom created in the simulation environment CST Microwave Studio. The phantom is created from MRI images of real patient with resolutions of 0.5 mm × 0.5 mm × 0.5 mm. Then, a temperature simulation is carried out based on the...
A method that uses microwave pulses to achieve strain imaging of the breast is presented. In the proposed method, the breast is inserted in an enclosure that defines the boundary conditions for the breast deformation under the influence of external pressure. The upper plate of the enclosure, which also includes an antenna array, is attached to a compression tool, whereas the lower and the front plates...
A theoretical model is presented to investigate the possibility of using a hybrid imaging method for early breast cancer detection. It uses the combined microwave and acoustic excitations to exploit contrasts in both the dielectric and elastic properties of malignant and normal breast tissues. The calculated results presented in this paper show that value of the scattering contrast between the malignant...
Recent years have seen an increased interest in ultra wideband (UWB) microwave imaging systems as an important alternative for mammography and other techniques such as magnetic resonance imaging or ultra sound in breast cancer detection. The reason is that microwaves offer a safe and low cost option for patients screening in comparison with these alternatives [1, 2]. The feasibility of UWB microwave...
Microwave breast imaging techniques have been proposed over the past few years because of their potential for breast cancer diagnosis. The basis is the high contrast in electrical properties between malignant and normal human breast tissues at the microwave frequency region. The observed high contrast is due to significantly different fluid contents, sodium concentrations, and electro-chemical properties...
The paper reports on experimental investigations into microwave properties of various materials that can be used to imitate real tissues in a breast phantom for testing an ultra wide band breast cancer radar detection system. The experiments involve an open ended probe technique to measure permittivity of selected materials across an ultra wide frequency band from 2 to 15 GHz.
