Ultrasound therapy system

Table of Contents

The use of ultrasound in physical medicine dates back to the late 1930's (Pohlman, et al, 1939). After the Second

World War, great interest was shown in this technique and many technical papers were presented. By 1955, the

council on Physical Medicine and Rehabilitation of the American Medical Association recommended the technique

as an adjunctive therapy for the treatment of pain, soft tissue injury and joint dysfunction, including osteoarthritis,

periarthritis, bursitis, tenosynovitis and a variety of musculoskeletal syndromes. Ultrasound therapy is currently

used on a very frequent basis in physical medicine. The Omnisound

the clinician with an accurately calibrated ultrasound source capable of operating in pulsed or continuous modes at

1.0 MHz or 3.0 MHz for therapeutic applications.

Ultrasonic therapy devices generally consist of a generator and a transducer. The generator produces the electrical

drive output to the transducer and provides measurement of its ultrasonic output. The transducer converts the

electrical energy from the generator into mechanical vibrations, known as ultrasonic vibrations. These vibrations are

then coupled to the patient's tissue via a coupling medium such as ultrasonic gel, water or mineral oil. When

electrostimulation is used simultaneously with ultrasound through the transducer the coupling medium must also be

conductive.

SCHEMATIC REPRESENTATION OF A TYPICAL ULTRASOUND GENERATOR

Typically therapeutic ultrasound generators operate in the 500 kHz to 3.5 MHz range. The frequency of the

ultrasonic wave will determine the absorption by the tissue and thus the penetration of the beam in the tissue.

Output intensities of 0.1 - 3 watts/cm
