dc.description.abstractSurgically implanted thermoregulating ferromagnetic seeds as a mean of inducing hyperthermia in malignant tumors has been successfully introduced in a clinical environment at the University of Arizona. This work covers topics in quality assurance for the method on two levels. The first level deals with the magnetic induction system where magnetic and electric fields are measured. A discussion on safety levels for patients and treatment personnel is given, and an optically coupled probe for magnetic field measurements is described. The second level treats the electrical characteristics of the ferromagnetic seeds. Systems to measure the permeability and conductivity of the seeds are presented with some typical results. Finally, hysteresis power loss in a seed is measured and compared to losses due to eddy currents.
