3D breast cancer imaging using holographic microwave interferometry

Abstract

Due to the critical need for complementary or alternative modalities to current X-ray mammography for early-stage breast cancer detection, a 3D holographic microwave imaging array (HMIA) system has been developed. This work describes how 3D images can be reconstructed from the 3D breast intensity distribution using holographic microwave and aperture synthesis imaging techniques. The obtained 3D simulation results have demonstrated the feasibility and superiority of detecting small malignant breast tumours using the proposed random antenna array. Simulation results demonstrate that the proposed technique has the potential to detect tumours of various sizes at various locations.

Imaging of 3-D Dielectric Objects Using Far-Field Holographic Microwave Imaging Technique

“…The presented antenna array in this paper provides the maximum combination of receiving antennas and enables the collection of out of plane transmission data [24,25]. Optimization of antenna array configurations to generate high resolute images is detailed in [27].…”

“…We do not need to use broadband systems and measurements like UWB radar methods. A matching medium was not required in this preliminary 2-D HMI measurement system [22][23][24][25], only air, which greatly simplified the practical implementation of such a system and reduced the associated cost. However, this claim needs further substantiation when the system is used with real biological tissues.…”

“…This paper demonstrates a new 3-D imaging algorithm based on our developed 2-D imaging method [21][22][23][24][25][26][27][28]. The 2-D HMI method was proposed based on holographic and aperture synthesis imaging techniques.…”

Three-Dimensional Far-Field Holographic Microwave Imaging: An Experimental Investigation of Dielectric Object

“…These measurements are repeated for every new A computer with MATLAB software is used to analyse the reflected singles and perform 3-D image of the object under test by using the developed 3-D HMI imaging algorithm. The development of HMI imaging algorithms and numerical simulation investigations are reported in [30][31][32][33][34][35][36][37].…”

“…However, this technique has one major limitation of missing detection small lesions if more than one lesion is located at the same x and y coordinates but at different z-planes. To overcome this limitation, we developed 3-D HMI imaging method [33][34][35].…”
