Abstract A refined version of the nonmetallic thermocouple (NM'T) is presented along with
results of microwave dosimetric testing of the
device in a practical laboratory environment. A smaller device was achieved
by using coaxial conductors of a dissimilar nature, and a slightly modified,
commercially available electronic ice point provided temperature compensation
of the secondary junctions adequate for normal laboratory use. Results of
practical dosimetric comparisons in
tissue-equivalent material between the coaxial NMT and a widely used, more
sophisticated temperature probe showed mean specific absorption rate (SAR) to
vary between 13.6% and 31 %, but no statistically significant difference was
observed in instances where the probes were compared at identical locations
during irradiation. |
