labs requested
patient in room pre-scanning

Cavitation
result of pressure changes in soft tissue causing formation of gas bubbles
stable
transient
MI
Stable cavitation
involves microbubbles already in soft tissue
change diameter with passin gof pressure variations of sound wave
Transient Cavitation
occurs when the microbubble collapses
produces pressure shockwaves
localized extremely high temps and light emission in clear liquids
potential for significant destructive effects
MI
Mechanical Index
indicator of cavitation
In-vivo
latin for
within the living
experimentation using a whole living organism
In-vitro
in glass
experimentation inside a test tube or lab dish
