Classification applied to brain haemorrhage detection: Initial phantom studies using electrical impedance measurements
McDermott, Barry; O'Halloran, Martin; Santorelli, Adam; McGinley, Brian; Porter, Emily (EIT2018, 2018-06-11)Machine learning and classification algorithms are applied to data collected from an EIT system. The system is used with an anatomically accurate head phantom setup in a variety of situations modelling normal and haemorrhagic ... -
Comparison of radar-based microwave imaging algorithms applied to experimental breast phantoms
Elahi, Muhammad Adnan; Lavoie, B. R.; Porter, Emily; Glavin, Martin; Jones, E.; Fear, E. C.; O'Halloran, Martin (Union Radio-Scientifique Internationale, 2017-08-19)Microwave imaging is a promising imaging modality for the early detection of breast cancer. The two most important signal processing components of a radar-based microwave imaging system are the early-time artifact removal ... -
Dielectric properties of bones: A potential indicator for osteoporosis
Amin, Bilal; Elahi, Muhammad Adnan; Porter, Emily; Shahzad, Atif; O'Halloran, Martin (National University of Ireland Galway, 2018-01-26)Osteoporosis is one of the major bone disease that results into bone fragility and fractures. Approximately 300,000 people over the age of 50 years suffer from osteoporosis in Ireland. Osteoporosis is mainly caused due ... -
Early-stage dielectric characterisation of renal cell carcinoma for positive surgical margin detection
La Gioia, Alessandra; Elahi, Adnan; Bottiglieri, Anna; Istuk, Niko; Dowling, Catherine; D'Arcy, Frank; O'Halloran, Martin; Porter, Emily (Institute of Electrical and Electronics Engineers, 2019-03-31)Partial nephrectomy is preferred to total nephrectomy tor clinically localised renal cell carcinoma. In order to minimise the risk of local tumour recurrence after partial nephrectomy, ideally, the surgical margins of the ... -
Electrical impedance tomography with exploitation of symmetry
McDermott, Barry; Porter, Emily; Jones, Marggie; McGinley, Brian; O'Halloran, Martin (Bioengineering in Ireland 2018, 2018-01-26)Electrical Impedance Tomography (EIT) is an imaging technique involving an electrode array positioned around the area of interest. Alternating current is injected, and voltage measured, between electrode pairs in a prescribed ... -
Examination of the sensing radius of open-ended coaxial probes in dielectric measurements of biological tissues
La Gioia, Alessandra; Porter, Emily; O'Halloran, Martin (Institute of Electrical and Electronics Engineers, 2017-07-09)A number of emerging electromagnetic diagnostic and therapeutic devices are designed based on estimates of benign and malignant tissue dielectric properties at different frequencies and temperatures. Accurate tissue ... -
