Single radiofrequency source for MR and hyperthermia studies
نویسنده
چکیده
Hyperthermia is an experimental/adjuvant therapeutic modality for cancer. Combining hyperthermia with the non-invasive metabolic studies using magnetic resonance (MR) is an interesting area of research and can provide useful information. In this paper, feasibility of using the same radio frequency source for carrying out combined hyperthermia and MR studies is demonstrated. A conventional RF hyperthermic applicator has been evaluated for use as an MR transmit/receive coil.
