Introduction to Ultrasound Therapy

Utilizing ultrasound waves through muscle, nerve and connective tissue has been well documented as
effective in reducing pain, muscle spasms and joint contractures.

There are several items that affect the penetration of ultrasound on the target tissues. Please refer to
the literature as a reference on the appropriate frequency for your clinical needs.

There are three ultrasound applicators available with the Intelect US: 2cm

2

, 5 cm

2

and 10cm

. You may

select either 1 or 3.3 MHz frequencies for each ultrasound applicator. Frequency may be selected
either before or during treatment.

Intelect Legend Ultrasound Clinical Features

Electronic Signature

Automatically calibrates the system to any size Intelect Legend sound head.

Head Warming

A feature traditionally available in more expensive brands of ultrasound. This will help curb the 
anxiety of patients during the first moments of treatment.

Ergonomic Applicators

A new easy to handle applicator that offers a 20 degree contour in the hand grip. This 
ergonomic extra will help deliver uniform ultrasound wiht greater clinician comfort.

Tactile Touch Control

Digitial electronics and new user interface design give you simple tactile touch control of all 
system parameters.

One-Two-Go Format

In two steps you are ready to start therapy.

• Programmable Start-Up Presets

All power-up presets can be individually customized to meet the clinician’s needs.

General Setup Steps

The unique design of the front panel allows you to set up a treatment faster than ever. Careful 
grouping of treatment options allow you to easily indentify and select from the appropriate options for
a specific mode of treatment. Two simple steps are all that’s needed prior to touching Start and 
initiating treatment.
