Classification applied to brain haemorrhage detection: Initial phantom studies using electrical impedance measurements
(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
(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 ...
Electrical impedance tomography with exploitation of symmetry
(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 ...
A novel tissue-mimicking material for phantom development in medical applications of EIT
(EIT2017, 2017-06-21)
A solid Tissue-Mimicking Material (TMM) with adjustable conductivity properties, which can be matched to those of biological tissue, is presented. TMM models of breast fat and gland matching the conductivity of real tissue ...
Realistic 3D finite element mesh of the adult human pelvis for electrical impedance tomography
(Zenodo, 2017-06-21)
The finite element method is a numerical technique
used to solve forward models for electrical impedance tomography.
To date, realistic finite element models (FEMs) have
been created for the head and thorax, but pelvic ...
Impact of radial heterogeneities of biological tissues on dielectric measurements
(Curran Associates Proceedings, 2017-09-11)
The dielectric properties of biological tissues are relevant in dosimetry studies and in radio-frequency and microwave medical applications. Broadband tissue dielectric data is commonly acquired using open-ended coaxial ...
Examination of the sensing radius of open-ended coaxial probes in dielectric measurements of biological tissues
(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 ...
Early-stage dielectric characterisation of renal cell carcinoma for positive surgical margin detection
(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 ...
Dielectric properties of bones: A potential indicator for osteoporosis
(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 ...
Significance of heterogeneities in accurate dielectric measurements of biological tissues
(Union Radio-Scientifique Internationale (URSI), 2017-08-19)
Accurate knowledge of the dielectric properties of biological tissues is necessary for the design and development of electromagnetic medical technologies; these properties quantify the accuracy and efficacy of system ...
