    • 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 ...

    • Anthropomorphic calcaneus phantom for microwave bone imaging applications 

      Amin, Bilal; Shahzad, Atif; Kelly, Daniel; O'Halloran, Martin; Elahi, Adnan (Institute of Electrical and Electronics Engineers, 2020-10-09)
      Recent studies have found a significant dielectric contrast between healthy and osteoporotic human trabecular bones. This dielectric contrast can be exploited by microwave imaging for monitoring human bone health. The ...

    • 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 ...

    • Dielectric characterization of ex vivo ovine and human adrenal glands for microwave thermal ablation applications 

      Bottiglieri, Anna; Shahzad, Atif; Donlon, Padraig; Dennedy, Micheal Conall; Lowery, Aoife; O'Halloran, Martin; Farina, Laura (Institute of Electrical and Electronics Engineers, 2021-01-15)
      Historically, adrenal glands diseases causing hypertension, such as Primary Aldosteronism (PA), have been treated through pharmacotherapy or surgical resection. Given the shortcomings of the available treatment options, ...

    • 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 ...

    • 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 ...

    • Minimum information for dielectric measurements of biological tissues (MINDER): A framework for repeatable and reusable data 

      Porter, Emily; La Gioia, Alessandra; Salahuddin, Saqib; Decker, Stefan; Shahzad, Atif; Elahi, M. Adnan; O'Halloran, Martin; Beyan, Oya (Wiley, 2017-11-13)
      The dielectric properties of biological tissues characterise the interaction of human tissues with electromagnetic (EM) fields. Accurate knowledge of the dielectric properties of tissues are vital in EM‐based therapeutic ...

    • A multistage selective weighting method for improved microwave breast tomography 

      Shahzad, Atif; O'Halloran, Martin; Jones, Edward; Glavin, Martin (Elsevier, 2016-08-24)
