Ultrasound Outline What is Ultrasound ? 1. Sound wave physics 2. Sound energy and its effect on soft tissue Pulsed non-thermal Ultrasound enhance tissue healing Cavitation and microstreaming Continuous thermal Ultrasound Contraindication & precautions Clinical judgment and dosage Literature Review with a grain of salt PLEASE!!! WHAT IS Ultrasound ? Ultrasound is a sound wave that has a frequency greater than 20 KHz. It is generated by applying an alternate current to a piezoelectric crystal (found in the transducer in the sound head). This crystal contracts and expands at the same frequency at which current changes polarity. The sound field generated by this crystal in turn makes the molecules in the sound field vibrate and oscillate. The crystal commonly used in US units is synthetic plumbium zirconium titanate (PZT). The quality of the crystal is what makes your US expensive. Crystal quality depends on the following: Beam Nonuniformity ratio: ranges from 2 to 6 the smaller the better.
