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 ...
Experimental evaluation of the effective ablation zone on ex-vivo bovine liver samples
(IEEE, 2018-09-10)
Microwave thermal ablation is under investigation
for minimally invasive treatments. In the cases of small targets,
such as adrenal glands, microwave thermal ablation is a valuable
alternative to the traditional and ...
Broadband dielectric properties of adrenal gland for accurate anatomical modelling in medical applications
(IEEE, 2017-09-11)
Dielectric properties of biological tissue are important in safety assessment and evaluation of novel medical imaging and therapeutic devices. This paper reports frequency dependent dielectric properties of adrenal tissue, ...
Tackling hypertension via adrenal ablation-the development of novel immunohistochemical ablation biomarkers
(IEEE, 2018-04-09)
Microwave thermal ablation is under consideration for minimally invasive treatment of unilateral and bilateral adrenal adenomas, symptomatic of Conn's syndrome. Currently available microwave technologies are illsuited to ...
An insight into bone dielectric properties variation: a foundation for electromagnetic medical devices
(Institute of Electrical and Electronics Engineers, 2018-09-10)
Dielectric properties of bones have recently got significant attention to monitor bone quality. This paper reports in-vitro dielectric properties of human trabecular bone samples obtained from osteoporotic and osteoarthritic ...
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 ...
