Technical aspects of microwave thermotherapy

We describe our new technical results dealing with microwave thermotherapy (hyperthermia) in cancer treatment, see Refs. [S.B. Field, C. Franconi (Eds .), Physics and technology of hyperthermia, NATO Seminar Proceedings, Urbin o, Italy, 1986; J. Hand, J.R. James (Eds.), Physical Techniques in Clinical Hyperthermia, Wiley, New York, 1986; J. Vrba, M. Lapes, Microwave Applicat ors for Medical Purposes, CTU Press, 1996, in Czech; J. Vrba, C.]Franconi, M. Lapes, Theoretical limits for the penetration depth of the intracavitary applicators, International Journal of Hyperthermia, 12::6 (1996) 737-742; C. Franconi, J. Vrba, F. Montecchia, 27 MHz hybrid evanescent-mode applicat ors with flexible heating field for deep and safe subcutaneous hyperthermia , International Journal of Hyperthermia, 9:5 (1993) 655-6741.]. Our researc h interest is to develop applicators for deep local heating and for intraca vitary cancer and/or prostate treatment as well. Further, a system for 3D S AR distribution measurements in water phantom is explained. Basic evaluatio n of clinical results is given. (C) 1999 Elsevier Science S.A. All rights r eserved.
