Challenges of post-measurement histology for the dielectric characterisation of heterogeneous biological tissues
La Gioia, Alessandra; O'Halloran, Martin; Porter, Emily (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 ... -
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 ... -
Impact of radial heterogeneities of biological tissues on dielectric measurements
La Gioia, Alessandra; Porter, Emily; Salahuddin, Saqib; O'Halloran, Martin (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 ... -
Investigation of histology radius for dielectric characterisation of heterogeneous materials
La Gioia, Alessandra; O'Halloran, Martin; Elahi, Muhammad Adnan; Porter, Emily (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 ... -
Sensing radius of an open-ended coaxial probe for dielectric measurement of tissues: Calculation with relative permittivity versus conductivity
La Gioia, Alessandra; O'Halloran, Martin; Porter, Emily (Institute of Electrical and Electronics Engineers, 2019-03-09)The dielectric properties of biological tissues are important parameters used in the design and optimisation of electromagnetic-based medical technologies. Typically, these parameters are measured ex-vivo using the open-ended ...
