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...
This paper presents a method for constructing a biomechanical breast model which does not require an initial time- and labour-intensive segmentation of the breast tissue. This is achieved by mapping voxel intensity and enhancement levels directly to Youngpsilas modulus values characteristic of the respective tissues. We demonstrate this new method by incorporating it into a biomechanically based registration...
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...
In this paper, the E-Pulse technique has been successfully applied on breast tumor detection. Numerical examples on a breast model with dispersive dielectric properties demonstrated that the E-Pulse technique can be applied to the problem. Introduction of the skin layer into the breast model and the inhomogeneous properties of the breast tissue would be the subject of further investigations
