Reconstrunction strategies for microwave imaging of breast; Reconstructions constrained to the breast domain
Paper in proceedings, 2017

In this paper an image reconstruction system and an algorithm for image reconstruction is developed and studied. The purpose is to determine and optimize a reconstruction scheme that is suitable for microwave imaging of breasts, with the purpose to diagnose breast cancer tumors. The present study is based on data generated from realistic breast models and in particular the use of different matching medium and constraining the reconstruction to within the breast region is studied. A time domain FDTD based reconstruction method is used. We conclude that the choice of matching liquid in imaging systems is important and largely affects the image quality, there is also a clear advantage of using a constrained reconstruction domain. A general conclusion is that particular adaptations in the imaging scheme can make the imaging result more robust and allow for a wider range of potential imaging scenarios.
