INDUCTIVE APPLICATOR
Depth of Penetration
Pulsed shortwave with magnetic field monode drum inductive applicators should be used to treat deeper tissue.
Penetration depth for fat at 27 MHz is approximately 62.6 inches (159cm) whereas depth for muscle is 5.5 inches
(14cm). This is somewhat modified by the SAR (Specific Absorption Rate) of the applicator and the method of
application.
For inductive field applicators, if the drum inductive applicator is in direct contact with the skin (with a towel layer
in between), the primary effects will be in a field formed from the surface to a depth of 2 inches (5cm).
Thermal and Subthermal Dosage
Pulsed shortwave diathermy provides outputs capable of producing thermal or subthermal effects. Average power
output in watts is controlled by the peak power and the duty factor. The duty factor is controlled by the pulse
duration and the pulse rate. The higher the average output, the greater the thermal effects in the tissue.
AVERAGE POWER (WATTS) = PEAK POWER (WATTS) x DUTY FACTOR
DUTY FACTOR = PULSE RATE (PPS) x PULSE DURATION (
sec)
