THE MULTIFREQUENCY ULTRASOUND IN CLASS E biomedical instrumentation

Fisiosonic Plus ® is a new device for ultrasound therapy, using an innovative output stage called Class E. The mechanical efficiency obtained through the output stage in Class E is decidedly higher than the one that can be obtained by means of traditional output stages and allows the operator to issue high powers on the patient in a constant and controlled way in relation to impedance of the tissues and with a limited thermal effect. Fisiosonic Plus ® is a last generation ultrasound device that uses 1-3MHz multifrequency applicators. These frequencies can be used separately or in joint mode during...
