    • Adaptive artifact removal for selective multistatic microwave breast imaging signals 

      Elahi, Muhammad Adnan; Glavin, Martin; Jones, Edward; O'Halloran, Martin (Elsevier, 2017-02-01)
      Microwave imaging is one of the most promising alternative breast imaging modalities. Early-stage artifact removal is an important signal processing component of a microwave breast imaging system. In this paper, a monostatic ...
    • An anatomically accurate dielectric profile of the porcine kidney 

      Salahuddin, Saqib; La Gioia, Alessandra; Shahzad, Atif; Elahi, Muhammad Adnan; Kumar, Arun; Kilroy, David; Porter, Emily; O'Halloran, Martin (IOP Publishing, 2018-02-26)
      Microwave ablation is a promising treatment for kidney cancer. Accurate knowledge of the dielectric properties of biological tissues is vital for quantifying the safety, reliability and accuracy of ablation, among other ...
    • Dielectric characterization of diseased human trabecular bones at microwave frequency 

      Amin, Bilal; Shahzad, Atif; Farina, Laura; Parle, Eoin; McNamara, Laoise; O'Halloran, Martin; Elahi, Muhammad Adnan (Elsevier, 2020-02-07)
      The objective of this study is to determine whether in vitro dielectric properties of human trabecular bones, can distinguish between osteoporotic and osteoarthritis patients' bone samples. Specifically this study enlightens ...
    • A feasibility study on microwave imaging of bone for osteoporosis monitoring 

      Amin, Bilal; Shahzad, Atif; Crocco, Lorenzo; Wang, Mengchu; O'Halloran, Martin; González-Suárez, Ana; Elahi, Muhammad Adnan (Springer, 2021-03-30)
      The dielectric properties of bones are found to be influenced by the demineralisation of bones. Therefore, microwave imaging (MWI) can be used to monitor in vivo dielectric properties of human bones and hence aid in the ...
    • Investigation of histology radius for dielectric characterisation of heterogeneous materials 

      La Gioia, Alessandra; O'Halloran, Martin; Elahi, Muhammad Adnan; Porter, Emily (Institute of Electrical and Electronics Engineers, 2018-07-13)
      Knowledge of the dielectric properties of biological tissues is fundamental in the design of novel electromagnetic-based medical devices. Tissue dielectric properties are typically measured using the open-ended coaxial ...
    • An investigation of the variation of dielectric properties of ovine lung tissue with temperature 

      Bonello, Julian; Elahi, Muhammad Adnan; Porter, Emily; O'Halloran, Martin; Farrugia, Lourdes; Sammut, Charles V. (IOP Publishing, 2019-06-24)
      Presently, lung cancer is the leading cause of cancer deaths. Microwave thermal ablation is commonly used for the treatment of lung cancer. During microwave ablation treatment, changing temperatures (up to 100 °C) cause ...
    • Microwave bone imaging: A preliminary investigation on numerical bone phantoms for bone health monitoring 

      Amin, Bilal; Shahzad, Atif; O'Halloran, Martin; Elahi, Muhammad Adnan (MDPI, 2020-11-05)
      Microwave tomography (MWT) can be used as an alternative modality for monitoring human bone health. Studies have found a significant dielectric contrast between healthy and diseased human trabecular bones. A set of diverse ...
    • Performance of leading artifact removal algorithms assessed across microwave breast imaging prototype scan configurations 

      Elahi, Muhammad Adnan; Curtis, C.; Lavoie, B.R.; Glavin, Martin; Jones, Edward; Fear, E.; O’Halloran, Martin (Elsevier, 2017-03-02)
      Microwave imaging is a promising imaging modality for the detection of early-stage breast cancer. One of the most important signal processing components of microwave radar-based breast imaging is early stage artifact ...
