Sažetak
The aim of this study was to investigate if the dielectric permittivity can be entirely preserved by freezing the biological tissue sample, which could significantly facilitate our measurement campaigns on excised tissues. For this purpose, we measured the permittivity of ex-vivo biological tissues: bovine brain white and grey matter, porcine brain white and grey matter, and the bovine liver, at 25°C, before and after they were frozen below -18°C and thawed back to 25°C. The liver permittivity was well preserved by the used freezing and thawing protocol. Unfortunately, the used protocol cannot be reliably used to prolong the life of the excised brain samples, as their permittivity changed after freezing and thawing.
