  • 3D printable solid tissue-mimicking material for microwave phantoms 

    McDermott, Barry; Porter, Emily; O’Halloran, Martin; Poudel, Anup; Biggs, Manus; Karode, Nireeksha S.; Coffey, Austin B. (IEEE, 2018-09-10)
    Phantoms provide valuable platforms for testing of medical devices including microwave diagnostic systems. This work describes a 3D printable solid tissue-mimicking material (TMM) for the production of such phantoms. The ...
  • Bi-frequency symmetry difference electrical impedance tomography a novel technique for perturbation detection in static scenes 

    McDermott, Barry; Avery, James; O'Halloran, Martin; Aristovich, Kirill Y.; Porter, Emily (IOP Publishing, 2019-02-20)
    Objective: A novel method for the imaging of static scenes using Electrical Impedance Tomography (EIT) is reported with implementation and validation using numerical and phantom models. The technique is applicable to regions ...
  • Brain haemorrhage detection through SVM classification of impedance measurements 

    McDermott, Barry; O'Halloran, Martin; Porter, Emily; Santorelli, Adam (NUI Galway, 2018-07-17)
    Machine Learning is becoming increasingly important in interpreting biological signals. In this work, we examine the potential for classification in brain haemorrhage detection. Numerical head and brain models with and ...
  • Detection of vesicoureteral reflux using electrical impedance tomography 

    Dunne, Eoghan; O'Halloran, Martin; Craven, Darren; Puri, Prem; Frehill, Paul; Loughney, Sarah; Porter, Emily (IEEE, 2018-12-14)
    Objective: The purpose of this study is to detect vesicoureteral reflux (VUR) non-invasively using electrical impedance tomography (EIT). VUR is characterized by the backflow of urine from the bladder to the kidneys. ...
  • Feasibility of water content-based dielectric characterisation of biological tissues using mixture models 

    Balduino, Roberta; McDermott, Barry; Porter, Emily; Elahi, Muhammad Adnan; Shahzad, Atif; O'Halloran, Martin; Cavagnaro, Marta (IEEE, 2019-01-23)
    This study quantitatively examines the validity of mixture formulae as models to describe the microwave-range dielectric properties of biological tissue of varying water content. Mixture formulae, specifically the Maxwell ...
  • Gamma band light stimulation in human case studies: Groundwork for potential Alzheimer's disease treatment 

    Jones, Marggie; McDermott, Barry; Oliveira, Bárbara Luz; O'Brien, Aoife; Coogan, Declan; Lang, Mark; Moriarty, Niamh; Dowd, Eilis; Quinlan, Leo; Mc Ginley, Brian; Dunne, Eoghan; Newell, David; Porter, Emily; Elahi, Muhammad Adnan; O' Halloran, Martin; Shahzad, Atif (IOS Press, 2019-05-27)
    It is known that proteins associated with Alzheimer's disease (AD) pathogenesis are significantly reduced by 40¿Hz entrainment in mice. If this were to translate to humans, verifying that such a light stimulus can induce ...
  • Static lesion detection in symmetric scenes using dual-frequency electrical impedance tomography 

    McDermott, Barry; O'Halloran, Martin; Porter, Emily (NUI Galway, 2019-01-18)
    Tissues have characteristic frequency dependent impendence to electrical current. This property is exploited by Electrical Impedance Tomography (EIT), an emerging biomedical imaging technique. In EIT, electrical conductivity ...
