Comparison of coaxial open-ended probe based dielectric measurements on ex-vivo thermally ablated liver tissue
Ruvio, Giuseppe; Farina, Laura; Bottiglieri, Anna; Eaton-Evans, Jimmy; Elahi, Muhamad Ednan; O'Halloran, Martin; Pinto, Rosanna; Lopresto, Vanni; Cavagnaro, Marta (Institute of Electrical and Electronics Engineers, 2019-03-31)This paper compares an in-house dielectric properties measurement system based on the "Stuchly and Stuchly" method with the broadly commercialised Keysight setup and existing literature for the characterization of ablated ... -
Dielectric characterization of ex vivo ovine and human adrenal glands for microwave thermal ablation applications
Bottiglieri, Anna; Shahzad, Atif; Donlon, Padraig; Dennedy, Micheal Conall; Lowery, Aoife; O'Halloran, Martin; Farina, Laura (Institute of Electrical and Electronics Engineers, 2021-01-15)Historically, adrenal glands diseases causing hypertension, such as Primary Aldosteronism (PA), have been treated through pharmacotherapy or surgical resection. Given the shortcomings of the available treatment options, ... -
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 ... -
Experimental evaluation of the effective ablation zone on ex-vivo bovine liver samples
Bottiglieri, Anna; Elahi, Adnan; Shahzad, Atif; Donlon, Padraig T.; Dennedy, Michael C.; O'Halloran, Martin (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 ... -
Exploiting tissue dielectric properties to shape microwave thermal ablation zones
Bottiglieri, Anna; Ruvio, Giuseppe; O’Halloran, Martin; Farina, Laura (MDPI, 2020-07-16)The dielectric characterization of tissue targets of microwave thermal ablation (MTA) have improved the efficacy and pre-procedural planning of treatment. In some clinical scenarios the tissue target lies at the interface ... -
Microwave thermal ablation: focusing energy in target tissue using fat layer
Bottiglieri, Anna; Farina, Laura; Shahzad, Atif; O'Loughlin, Declan; O'Halloran, Martin; Elahi, Muhammad Adnan (Institute of Electrical and Electronics Engineers, 2019-03-31)Microwave thermal ablation therapy is a minimally invasive technique introduced in the interventional oncology practice to treat a range of cancerous pathologies. Whereas satisfying results are obtained with the treatment ...
