A Compressive Sensing Approach for 3D Breast Cancer Microwave Imaging with Magnetic Nanoparticles as Contrast Agent

, 2016
In microwave breast cancer imaging magnetic nanoparticles have been recently proposed as contrast agent. Due to the non-magnetic nature of human tissues, magnetic nanoparticles make possible the overcoming of some limitations of conventional microwave ...

Quantitative microwave imaging based on a huber regularization [PDF]

, 2013
Reconstruction of inhomogeneous dielectric objects from microwave scattering by means of quantitative microwave tomography is a nonlinear, ill-posed inverse problem. In this paper, we employ the Huber function as a robust regularization approach for this

A Numerical Study on Optimal Multipole Order for Sparse Microwave Imaging of Star-Shaped Scatterers

, 2019
In this paper, we extend the work on higher-order sparse two-dimensional microwave imaging using transverse magnetic polarized fields. This approach is capable of retrieving the shape of concave targets, which is particularly interesting when imaging ...

Magnetic nanoparticles enhanced breast cancer microwave imaging via compressive sensing

, 2015
Magnetic nanoparticles have been recently proposed as contrast agent in microwave breast cancer imaging. As a matter of fact, being human tissues non-magnetic, their use would allow achieving a reliable and specific diagnosis of breast cancer, by ...
