Bi-Frequency Symmetry Difference (BFSD) EIT in stroke diagnosis
BFSD-EIT can detect deviations in the inherent normal symmetry of the head due to, for example, the presence of a bleed or clot in stroke. We assess the potential of BFSD-EIT to robustly detect lesions under a series of ...
Feasibility of water content-based dielectric characterisation of biological tissues using mixture models
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 ...
Brain haemorrhage detection through SVM classification of impedance measurements
(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 ...
Bi-frequency symmetry difference electrical impedance tomography a novel technique for perturbation detection in static scenes
(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 ...
Detection of vesicoureteral reflux using electrical impedance tomography
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. ...
Static lesion detection in symmetric scenes using dual-frequency electrical impedance tomography
(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 ...
