Number of echoes within a structure
Anechoic

Echotexture
Arrangement of echoes within a structure
Homonegous
Uniform structure or composition trhoughou
Heterogenous
Dissimilar composition appearing irregular or variegated
Echopattern

Image resolution
Ability to distinguish between two adjacent structures
Acoustic window
Area of patient that enhance us transmission and provides optimal scanning access to the area of interest
Acoustic impedance
Property of all substances and equal to product of the tissue density and the speed of sound
Process of attenuation
Process that occurs as a sound wave travels througha medium
ALARA principle
As low as reasonably achievable, keeping power exposure time to a minimum while acquiring the necessary clinical information
