title: A comparison of swine abdominal temperature distribution after heating with BSD-1000, an annular phased array system (APAS), and Thermotron RF-8.
abstract: External hyperthermia for deep-seated tumors is still a difficult problem. We compared the abdominal temperature distribution in a pig after heating with BSD-1000, an annular phased array system (APAS), and Thermotron RF-8. Thirty elastic tubes were inserted into the upper abdomen of the pig and a thermocouple was inserted into each of the tubes. After heating, these thermocouples were moved at 1-cm intervals and the three-dimensional temperature distribution was obtained. The temperature distribution after heating with APAS and Thermotron RF-8 was compared by using the distribution on the longitudinal center line of each sagittal plane at 1-cm intervals from the center. The temperature was much higher and its distribution more homogeneous with APAS than Thermotron RF-8.
