the science of sound, including its production, propagation and effects
an area of increased echo intensity distal to a fluid filled area
a mechanical disturbance which propagates through a continuous medium
any medium or structure that transmits sound well
no internal echoes
part of an ultrasound image that does not accurately represent the underlying anatomy
progressive weakening of the sound beam as it travels through body tissue
color flow imaging
ability to display bood flow in multipe colors depending on the velocity, direction of flow...
a structure that has both fluid filled and solid components
concern s the behavior of high frequency sound waves as they are reflected off moving fluid,...
the simultaneous display of a gray scale image and the Doppler waveform
a recorded acoustic signal
a region containing a high amount of echoes
number of cycles per second
does not have a uniform texture
used in the sense of having a uniform texture
a region containing many echoes, used mainly to describe an area in relation to its surrounding...
a region that contains only a few echoes, used maily to descrie a area in relation to its surrounding...
surface forming the boundary between different structures
of the same echogenicity as a neighboring area, but not necessarily of the same texture
a general term for the tissue of an organ
real time imaging
type of imaging in which many frames are run together to create a cinematic view of the tissue

twisting the transducer in a circular motion while holding it in one place
shape of the image on the film, depends on the type of transducer that is used
failure of the sound beam to pass through an object, causing the absense of echoes posterior
defines a mass with no fluid areas
a device capable of convering energy from one form to another
sound waves which have a frequency above the audible range of the human ear
