Cavitation is the process of creating and collapsing tiny bubbles or voids in a liquid, usually through the application of high-intensity sound waves. Cavitation can occur in various forms, such as ultrasonic cavitation and hydrodynamic cavitation. In the context of medicine, cavitation is used in procedures like histotripsy, lithotripsy, and oncotripsy to break up tissue or stones in the body using high-intensity ultrasound waves.

It's important to note that cavitation is a physical process that occurs in liquids and is not related to the phenomenon of electromagnetic (EM) radiation. EM radiation is a type of energy that travels through the vacuum of space or through various materials in the form of waves. EM radiation includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

Cavitation cannot be used to "rupture" or "cavitate away" EM radiation in the same way that it can be used to break up tissue or stones. Instead, EM radiation can be absorbed, reflected, refracted, or transmitted through various materials, depending on the properties of the material and the frequency of the radiation. It's also worth noting that EM radiation does not require a medium to travel through, unlike sound waves, which need a medium (such as a gas, liquid, or solid) to propagate.
