A theoretical model for the biomechanical properties of breast tissues under the influence of acoustic signal is derived and validated. That model is employed in a microwave imaging method that aims at extracting the three-dimensional biomechanical properties of breast. The high contrast in the biomechanical properties between healthy and malignant tissues represents the basis of the presented imaging...
This paper discusses the development of an artificial heterogeneous breast phantom that emulates the electrical properties of human breast over the ultra wideband frequency range of 3.1GHz to 10.6GHz. The developed breast phantom has a realistic hemispherical shape and dielectric properties which are close to those of the different real breast tissues. This artificial breast phantom is to be used...
The initial results for using ultra wideband pulse to achieve strain imaging of breast are presented. In the proposed method, the breast is inserted between two horizontal plates. The upper plate, which includes an array of ultra wideband antennas, is attached to a pressing tool, whereas the lower plate is fixed. Each of the antennas at the top plate is used to send an ultra wideband pulse to penetrate...
