Evaluation of temperature fields in two dynamic phantoms heated by the ferromagnetic implant hyperthermia

Lim, Junghwan, 1961- January 1988 (has links)
Two experimental dynamic phantoms have been used for studying temperature distributions induced by interstitial ferromagnetic implant hyperthermia at various blood perfusions, Curie point implants, and input power levels. One of the phantoms is an axially perfused hollow cylinder filled with 3 mm diameter glass beads, and the other is a similar cylinder model that is radially perfused. Analytic models have been developed for evaluating temperature profiles within the two phantoms. Experimental results from the phantoms compare reasonably well with the analytical results. A qualitative comparison is made between thermal profiles derived from both a convection energy equation, for a homogeneous porous medium, and a bioheat transfer equation. The adequacy of using a porous material for simulating living tissue is discussed. Parametric studies showing the effects of various implant parameters such as Curie point and applied power are analyzed.
