VIDEO: US-Ripples
Dr. Lew reviews the ultrasound on the Chattanooga Intellect Machine and demonstrates how the different duty cycles changes how the sound waves of ultrasound cause ripples in water.

Key points:
1) How does a 20% duty cycle differ from a 100% duty cycle in ripple formation?
2) How does a 1MHz differ from a 3.3MHz frequency in therapeutic ultrasound?
3) Which frequency is used to treat deep tissues?
4) Which duty cycle is used for continuous ultrasound?
5) What should a person feel with continuous ultrasound?
6) What is the ideal duty cycle with pulsed ultrasound?
7) What type of heat transfers occur with ultrasound?
