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...
Clinical results show that microwave based hyperthermia can dramatically improve the treatment outcome if combined with radiation and chemo therapy. During hyperthermia treatment it is necessary to monitor the heating in order to ensure that therapeutic temperatures are reached in the tumour, as well as to monitor hot-spots in non-tumour areas. Microwave imaging technology has the potential to be...
We study the effect of noise on microwave breast imaging by numerical simulations. A high contrast breast model is considered and the image reconstructions are carried out in time domain using a nonlinear inversion algorithm. A relative reconstruction error is defined in order to quantitatively evaluate the image distortion due to noise. The relative reconstruction errors of noisy reconstructions...
Microwave tomography is currently being researched for breast cancer detection. Our research has shown that clinical imaging preferably has to be made in a full 3D setting. In this paper we show results in order to evaluate the performance of a clinical system under construction.
Microwave imaging for breast cancer detection has been of significant interest for the last two decades. Recent studies focus on solving the imaging problem using an inverse scattering approach. Success of these methods relies on the quality of the forward data such that the tumor inside the breast volume is well illuminated. In this paper, a numerical study of the forward scattering data is conducted...
