Comments on "Investigation of Histology Region Dielectric Measurements of Heterogeneous Tissues"
Artikel i vetenskaplig tidskrift, 2020

In the article, "Investigation of histology region in dielectric measurements of heterogeneous tissues," by Porter and O'Halloran, the authors utilize a flexible phantom in a layered material dielectric property analysis to quantify the effective sensing volume of a coaxial dielectric probe. Ostensibly, this test has been used by others to characterize the region for which percent variation in the material composition in front of the probe corresponds to percent variation in the computed effective dielectric properties. By employing a compressible material, the authors fail to isolate features that are attributable solely to the probe, itself, and inadvertently incorporate confounding characteristics associated with the compressible nature of the material. The net effect is to exaggerate the probe's sensing volume, which undermines the conclusions drawn from the subsequent tissue dielectric property studies. © 2019 IEEE.
