摘要：

A general three-dimensional planning program has been developed for hyperthermia treatments for cancer.1 In this study, the program is used to analyze the three-dimensional temperature distributions generated by interstitial ferromagnetic implants. An empirical power absorption formula developed by Haider2 for thermally self-regulating nickel-silicon ferromagnetic seeds has been used to calculate the seed power absorption as a function of seed temperature. By properly choosing the seed type (Curie point of seeds), and by using appropriate seed spacing, this heating modality can generate desirable three-dimensional temperature distributions for many different situations over a fairly large range of blood perfusion values. Detailed information regarding the choice of the Curie points of the seeds and the seed spacing for certain blood perfusions is also given as a quantitative guide for treatment planning.
