Broadband dielectric properties of porcine lung as a function of temperature

Popis výsledku v původním jazyce

Computer modeling plays an important role in many aspects of microwave ablation technology development, including applicator design and ablation zone prediction for treatment planning. In order to increase the precision of models or to be able to assess the uncertainty of model predicted therapy outcome, the values of tissue dielectric parameters and dependency on temperature are required. While some data have previously been reported on temperature dependent dielectric properties of liver tissue properties, there is limited amount of information for other tissues, such as the lung. We report on the experimental measurement of broadband (500 MHz - 6 GHz) lung dielectric properties and their thermal dependency. Moreover, the dielectric properties of bovine muscle were measured as a control and validation of our measurement technique. Both relative permittivity and effective conductivity tend to decrease with rising temperature and their decay can be modelled by a linear function within the temperature range from 27°C to 94°C.
