| Summary: | Purpose. Currently (2022), the existing hyperthermia
installations are large. As a result, hyperthermia treatment
is carried out only where this equipment is located. In this
paper, a study is conducted aimed at creating a compact
hyperthermia device. Flat antennas in the form of a spiral for
heating the local area have been developed and investigated.
Calculations and simulation modeling for the developed
antennas have been carried out.
Materials and Methods. The materials and methods of
computational mathematics, ultrahigh frequency technology
and the theory of automatic regulation are used in the study.
Software is used to develop high-frequency systems.
Results. The directional patterns of the electric field of the
developed antennas are obtained. With the help of simulation
modeling, magnetic field strength distributions for the
developed antennas are constructed. It is established that
the maximum radiated power occurs when the oscillation
frequency is equal to the natural frequency of the antennas.
The nonlinear dependence of the supply voltage on the
radiation power is established. During the experiments, local
heating of the back area of the left forearm is carried out
using the developed antennas and a generator. The maximum
heating temperature is 41,5 °C.
Conclusion. The heating technology using a spiral antenna
and a generator makes it possible to heat local areas to
temperatures of the therapeutic range. The developed
generator circuit is turned out to be very easy to operate. The
maximum power of the generator is 3,2436 watts. The supply
voltage is 6,36 volts. Creating antennas on a biodegradable
film using an inkjet printer will allow you to create both
contact and non-contact heating. |
