A Preliminary Study on Detecting Tumor Boundaries with an Open-Ended Coaxial Probe

open access: yes2024 IEEE INC-USNC-URSI Radio Science Meeting (Joint with AP-S Symposium)
Various methods are used to determine the boundaries of malignant tissues. Frozen section analysis (FSA) is the most popular technique to determine tumour boundaries during surgical operation. In this study, open-ended coaxial probe (OECP) method was used to decide tumour boundaries according to dielectric properties.

Permittivity measurements using dual open ended coaxial probes

open access: yes, 2012
The motivation for this study has been to conduct a feasibility study on a measuring device to monitor hydrate formation close to the inner surface of a pipe where a multiphase hydrocarbon fluid mixture is flowing. This measurement device is supposed to measure both the permittivity and the conductivity of the fluid mixture, and estimate the hydrate ...
