Minimum information for dielectric measurements of biological tissues (MINDER): A framework for repeatable and reusable data
(Wiley, 2017-11-13)
The dielectric properties of biological tissues characterise the interaction of human tissues with electromagnetic (EM) fields. Accurate knowledge of the dielectric properties of tissues are vital in EM‐based therapeutic ...
Modeling of the dielectric properties of biological tissues within the histology region
(Institute of Electrical and Electronics Engineers (IEEE), 2017-11-27)
The dielectric properties of biological tissues characterize the interaction of electromagnetic fields with the human body. As such, accurate knowledge of these properties is vital to the design and development of ...
Challenges of post-measurement histology for the dielectric characterisation of heterogeneous biological tissues
(MDPI, 2020-06-09)
The dielectric properties of biological tissues are typically measured using the open-ended coaxial probe technique, which is based on the assumption that the tissue sample is homogeneous. Therefore, for heterogeneous ...
An anatomically accurate dielectric profile of the porcine kidney
(IOP Publishing, 2018-02-26)
Microwave ablation is a promising treatment for kidney cancer. Accurate knowledge of the dielectric properties of biological tissues is vital for quantifying the safety, reliability and accuracy of ablation, among other ...
Investigation of histology radius for dielectric characterisation of heterogeneous materials
(Institute of Electrical and Electronics Engineers, 2018-07-13)
Knowledge of the dielectric properties of biological tissues is fundamental in the design of novel electromagnetic-based medical devices. Tissue dielectric properties are typically measured using the open-ended coaxial ...
Effects of standard coagulant agents on the dielectric properties of fresh human blood
(Institute of Electrical and Electronics Engineers, 2017-11-27)
In this paper, the effects of coagulation and temperature on the dielectric properties of human blood are investigated over the frequency range of 400 MHz - 20 GHz using freshly extracted blood samples. The dielectric ...
Modelling the sensing radius of a coaxial probe for dielectric characterisation of biological tissues
(Institute of Electrical and Electronics Engineers, 2018-08-22)
The open-ended coaxial probe is the most common measurement tool used to dielectrically characterize biological tissues. Most healthy and malignant biological tissues are macroscopically heterogeneous, with the exception ...
Image-based classification of bladder state using electrical impedance tomography
(IOP Publishing, 2018-12-03)
Objective: In this study, we examine the potential of using machine learning classification to determine the bladder state ( not full , full ) with electrical impedance tomography (EIT) images of the pelvic region. Accurate ...
Heparin as an anticoagulant for the dielectric measurement of blood
(Institute of Electrical and Electronics Engineers, 2019-01-23)
Testing blood ex-vivo allows physicians to gain an understanding of what is happening within the human body. Once blood is extracted from the body, it begins to clot. This process can affect the outcome of blood tests, ...
Predicting the sensing radius of a coaxial probe based on the probe dimensions
(Institute of Electrical and Electronics Engineers, 2020-05-19)
The coaxial probe technique is used to acquire the dielectric properties of biological tissues in the microwave frequency range. To dielectrically characterize heterogeneous samples, the sensing radius of the probe must ...
