Comparison of in-vivo and ex-vivo dielectric properties of biological tissues
Salahuddin, Saqib; La Gioia, Alessandra; Elahi, Muhammad Adnan; O'Halloran, Martin; Shahzad, Atif (Curran Associates Proceedings, 2017-09-11)Accurate knowledge of the dielectric properties of biological tissues are crucial for various applications such as assessment of specific absorption rate and safety of electromagnetic medical devices. Most of the ... -
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 ... -
