Contrast-enhanced ultrasound (CEUS) is the application of ultrasound contrast medium to traditional medical sonography. Ultrasound contrast agents rely on the different ways in which sound waves are reflected from interfaces between substances. This may be the surface of a small air bubble or a more complex structure.
Ultrasound and microbubble treatment without additional drugs impeded the growth of small tumors but required a combinatorial drug treatment to affect medium-sized tumor growth. [54] With their immune stimulating mechanism, ultrasound and microbubbles offer a unique ability to prime or enhance immunotherapies for more effective cancer treatment.
The animal snaps a specialized claw shut to create a cavitation bubble that generates acoustic pressures of up to 80 kPa at a distance of 4 cm from the claw. As it extends out from the claw, the bubble reaches speeds of 60 miles per hour (97 km/h) and releases a sound reaching 218 decibels. The pressure is strong enough to kill small fish.
Bubble sensors are used to detect the presence of bubbles in fluid-filled tubes. They play a vital role in many fields, including medical technology, process control, pharmaceuticals, and the petroleum industry. The most common type of sensors used are ultrasonic or capacitor based. Bubble sensor for Extracorporeal Blood Circuits

Left to right: formation of bubble; slow expansion; quick and sudden contraction; purported fusion event. Bubble fusion is the non-technical name for a nuclear fusion reaction hypothesized to occur inside extraordinarily large collapsing gas bubbles created in a liquid during acoustic cavitation. The more technical name is sonofusion. [1]
