During this year’s EUCAP MyWAVE was represented during two convened sessions entitled “CA17115 (MyWAVE): Supporting Medical Device Development via Dielectric and Thermal Tissue Characterization” and “SW02: COST Session CA17115 (MyWAVE): Developments in Electromagnetic-Based Medical Technologies” organised by Dr Martin O’Hollaran & Dr Raquel C. Conceição and Dr Laura Farina & Dr Gennaro Bellizzi, respectively. The conference was held online between 15th and 20th March, 2020 and the following is a complete list of papers presented in both sessions.

- Peyman A. Dielectric properties of biological tissues at frequencies below 1 MHz. “At low frequencies, the dielectric values for biological tissues are difficult to determine due, at least partly, to the dependency of the dielectric properties on the physiological state of the tissues and changes occurring after death. In practice chemical interaction between the measuring probe and lossy material can cause several errors and uncertainties in the results. In an attempt to develop an advance black-platinum four-point electrode probe technology to measure impedance values of low concentration saline solutions, we have identified at least one major source of error namely, electrode polarisation and some other high-frequency effects as measurement artefacts that made the capacitive part of the dielectric data unreliable.” Taken from Technical Programme.

- Zia G, Sebek J, Prakash P. Broadband Dielectric Measurements of Ex-Vivo Uterine Fibroid Tissues over the Ablative Temperature Range. “Microwave ablation is under consideration as an energy modality for minimally-invasive treatment of uterine fibroids. Computational models of microwave ablation are useful for guiding the design of new devices and systems, but require tissue dielectric properties, including their variation at elevated temperatures, for accurate prediction of ablation profiles. This study reports on preliminary results of a study on experimental characterization of the broadband (0.5 – 6 GHz) dielectric properties of surgically excised uterine fibroids, with measurements taken at temperatures up to 155 ºC. The measured dielectric properties at elevated temperatures dropped considerably, likely due to the effects of tissue desiccation and water vaporization, similar to reports of dielectric property measurements for other tissues.” Taken from Technical Programme.

- Peyman A. Dielectric Properties of Tissues Historical Aspects and Measurement Challenges. “This paper reviews and summarises the state of knowledge on dielectric properties of tissues. Effect of ageing and pathological state of tissues on the dielectric properties are discussed as well as the impact of variation in dielectric data on the outcome of dosimetric studies. A critical analysis of the existing measurement techniques and uncertainty evaluation on the measured data are also presented. Finally, some unpublished data on dielectric properties of porcine abdominal tissues will be presented in light of rise in popularity of diagnostic imaging techniques utilising RF signals, and increase in demand for accurate in-vivo dielectric properties of abdominal tissues.” Taken from technical programme.

- Sebek J, Chamani F, Lakkireddy D, Prakash P. Characterization of Esophageal Temperature Profiles During Cardiac Radiofrequency Ablation. “Radiofrequency ablation is a widely used approach for treatment of symptomatic atrial fibrillation by achieving pulmonary vein isolation. A rare, but severe, complication associated with ablation is perforation of the esophageal wall, due to unintended passive heating, leading to esophageal fistulas. Several strategies for managing esophageal luminal temperatures during ablation have been proposed, with the objective of limiting thermal damage and preventing perforation. However, there remains a limited understanding of the relationship between esophageal luminal temperatures and temperatures on the serosal surface. Here, we report on measured temperature profiles in a custom ex vivo layered tissue preparation during radiofrequency ablation. Over n=82 ablations, temperatures on the mucosal surface of the esophagus ranged between 37-38.1 °C as serosal surface thermal doses ranged between 0-80 CEM43. These findings may contribute to the identification of safety thresholds for esophageal temperatures, which may preclude the incidence of esophageal perforation during cardiac ablation.” Abstract taken from Technical Programme.
