Abstract A microwave system has been developed
and characterized for delivering heat directly into tumors.
This system employs a microwave power source (3-10W) operating in the 500 MHz
to 1.3 GHz frequency range, coaxial transmission line, and a monopole
antenna. Absorbed power was measured in saline, in tissue equivalent
phantoms, and in tumors in live and dead mice.
Antennas were designed to operate at 500 MHz and 1 GHz, and the critical
design parameters have been identified for this system. Analytical and
experimental results obtained in our laboratory suggest that this system is
capable of providing controlled temperature distributions appropriate for
hyperthermia in animal tumors. Theoretical results
predict that 3 GHz may be an optimum choice for this system in animal tumors of approximately |
