dc.description.abstract | Accurate knowledge of the dielectric properties of biological tissues is necessary
for the design and development of electromagnetic medical technologies. Both electromagnetic
diagnostic and therapeutic techniques depend heavily on the dielectric properties of the tissues in
the region of interest. These properties quantify the accuracy and efficacy of systems, and enable
realistic modelling and simulation prior to clinical evaluation. Despite these strong needs, the
dielectric properties reported in the literature have suffered from significant inconsistencies. These
inconsistencies have mainly been attributed to clinical confounders that have not historically
been well-controlled. In this work, the sensing depth of the dielectric probe, a key clinical
confounder, is investigated using heterogenous biological samples composed of porcine muscle
and fat. Complex heterogeneous samples can contain several different types of tissues, which
are identified through histology. When measuring the dielectric properties, it is crucial to know
which tissues contribute to the measurements. In order to achieve this, a histology region is
used, which enables correspondence between complex tissue samples and the measured dielectric
properties. The histology region is given by the sensing depth in the longitudinal direction, and
the sensing radius in the radial direction. We perform dielectric measurements on heterogenous
samples and calculate the sensing depth of the dielectric probe for this measurement scenario.
We then examine how errors in the assumed sensing depth value affect quantification of the tissue
composition. This study demonstrates that the sensing depth, and thus the histology region, has
a significant impact on how we interpret the dielectric properties of a sample, indicating that
this region must be defined and measured with extreme care. With an improved understanding
of these parameters, more accurate and repeatable dielectric measurements will be possible, thus
facilitating the development of electromagnetic medical devices. | en_IE |
