Part-body hyperthermia
Part-body hyperthermia is a technique derived from the regional approach and further developed,to heat a selected anatomical region in an extended manner up to 41 – 42 °C under careful MR monitoring. For this application, three-dimensional multi-antenna applicators (derived from the applicators used in regional hyperthermia) are operated at higher power levels (typically above 1000 Watts) and are well controlled to extend the heated volume to a body region such as the whole pelvis, the whole abdomen or (if clinically desirable) the upper abdomen or lower thorax or others. At these higher power levels, use of MR-monitoring (to measure on-line temperature and perfusion) and a planning system are required to be safe. Systems for part-body hyperthermia are called hybrid systems because they are based on the MR-compatible integration of a multi-antenna applicator into an MR tomograph (“hybridisation“).
