Researchers in 1976 studied implanting metallic materials like carbon steel rods into brain tissue, then exposing the head to radiofrequency electromagnetic fields to create localized heating. They found that carbon steel rods and Hysterloy heated most effectively (about 1000 and 655 cal/g-min, respectively), with rods oriented parallel to the RF field producing the most heat. The goal was to combine targeted brain heating with chemotherapy to concentrate cancer drugs in tumors while keeping healthy tissue cool.
