Indications/Contraindications Indications Ultrasound for use in applying deep heat can be used for treatment of selected medical conditions such as the relief of pain, muscle spasms and joint contractures. Those conditions may be associated with adhesive capsulitis, bursitis with slight calcification, myositis and soft tissue injuries. The Intelect Legend ®...
Potential for Burns It is possible for ultrasound therapy to cause burns if the therapy is not performed properly. Skin burns can result from one or more of the following: • If the intensity (power) is too high. • If you are using too low a frequency. •...
Handle the Ultrasound Applicator(s) with Care • DO NOT drop the sound head on hard surfaces. • DO NOT allow the sound head to reach maximum temperatures repeatedly. • DO NOT cool an overheated sound head with ice water or ice packs. •...
. 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.
Power-Up Preset Parameters Frequency: 1 MHz Duty Cycle: Treatment Time: 5 Minutes Power: Clinician Controlled Quick Start The following is a quick step by step procedure for using ultrasound (US). Before proceeding refer to treatment cautions. Procedure Comments Turn power on The unit will go through self diagnosis, followed by the main menu.
Modifying Treatment Parameters Treatment parameters can be modified prior to or during a treatment session. To modify a parameter, select that parameter on the control panel. Treatment time and output intensity are changed using their designated up or down arrow buttons. Frequency, duty cycle and output display toggle from choice to choice with repeated touches of their respective buttons.

Description of Ultrasonic Field The spatial distribution of the radiated field is essentially a collimated beam of the ultrasonic energy having a cross-sectional area of 8.5 cm for the 10 cm sound head when measured at a point 5 mm from the transducer face.
Page 19
Beam Profile of the 5 cm Transducer Operating at 1 MHz and 3.3 MHz Spatial distribution of the radiated field is essentially a collimated beam of the ultrasonic energy having a cross-sectional area of 4.0 cm for the 5 cm sound head when measured at a point 5 mm from the transducer face.
Page 20
Beam Profile of the 2 cm Transducer Operating 3.3 MHz Spatial distribution of the radiated field is essentially a collimated beam of the ultrasonic energy having a cross-sectional area of 1.8 cm for the 2 cm sound head when measured at a point 5 mm from the transducer face.
Glossary Beam Non-Uniformity Ration – By nature, an ultrasound beam is not homogeneous. The BNR is a ratio of the highest intensity found in the beam field to the average intensity as indicated on the output dis- play of the unit. This measure may not exceed 6.0:1. Because of the areas of increased intensity, the sound head is moved continuously during the treatment.
