Direct realization of absorbed dose to water in diagnostic radiation via calorimetric methods poses many challenges since the thermal signal of interest may be less than a few microKelvin. In actual biological systems or structures, like the lung, there is the additional complication of tissue heterogeneity, which introduces a quasi-random component to the dose distribution, hence to thermal indicators that might be used for metrological purposes. In the present study, a first effort is made to simulate how such indicators might be analyzed for purposes of realizing absorbed dose to biological tissue models, by importing a lung model from Simpleware into COMSOL and running simulations involving the Heat Transfer Module.
