OPERATION
Ultrasound
Ultrasound is a form of mechanical energy that consists of high frequency vibrations delivered to
the body by means of an ultrasound beam emitted out of an applicator. These high frequency
vibrations pass through the tissues of the body and are gradually absorbed and transformed into
heat.
This temperature increase triggers biological changes to occur in tissues for the relief of pain,
relaxation of muscle spasms and reduction of joint contractures. The ultrasound frequency, duty
cycle and level of intensity can all be adjusted to produce the desired therapeutic effect.
Head Warming
is a unique feature of the Intelect® Legend Combo that allows the aluminum
surface of the Ultrasound applicator to warm up to room temperature, enhancing patient
comfort. Select

Frequency
of ultrasound determines the depth of penetration. One megahertz penetrates
approximately 2 inches, and 3 megahertz penetrates to .6 inches. Both 1 and 3.3 MHz frequencies
are available and can be changed throughout the course of treatment by selecting
frequency
and pressing
enter
.
Duty Cycle
is the ratio of on time to total time of the ultrasound and is expressed as a percent-
age. The options are 10%, 20%, 50% and 100% (Continuous-default). Select
