MICROWAVE DIATHERMY - Coggle Diagram
MICROWAVE DIATHERMY
Production of Microwaves
- Production of high frequency currents
-
- Special type of valve called a magnetron is used
.
- Warm-up required.
-
- HF – coaxial cable.
-
- Coaxial cable- a small aerial – Emitter or director or applicator.
Application
-
Physiological effects
Absorbed, transmitted, refracted or reflected
Absorption of the waves results in
the production of heat in the tissues
by means of dipole rotation and molecular distortion.
The effects deeper than infra-red irradiation,
but less than shortwave diathermy.
Microwaves are strongly absorbed by water
so tissues with good blood supply
such as muscle, moist skin, blood vessels, internal
organs and eyes
gets appreciable heating
than tissue with low fluid content like fat.
