The simulator was used to plan the treatment using safe, low energy x-rays, and fluoroscopic images for more sophisticated treatment planning. Likewise, Hyperthermia therapy equipment was purchased for $150,000. Hyperthermia is a technique of treating cancer by elevating the body temperature using microwaves both externally and internally.
