Side A ------ Side B
acoustics ------ the science of sound, including its production, propagation and effects
acoustic enhancement ------ an area of increased echo intensity distal to a fluid filled area
acoustic wave ------ a mechanical disturbance which propagates through a continuous medium
acoustic window ------ any medium or structure that transmits sound well
anechoic ------ no internal echoes
artifact ------ part of an ultrasound image that does not accurately represent the underlying anatomy
attenuation ------ 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 and extent of tubulence
complex ------ a structure that has both fluid filled and solid components
doppler ------ concern s the behavior of high frequency sound waves as they are reflected off moving fluid, usually blood. a waveform image is produced
duplex imaging ------ the simultaneous display of a gray scale image and the Doppler waveform
echo ------ a recorded acoustic signal
echogenic ------ a region containing a high amount of echoes
frequency ------ number of cycles per second
heterogeneous ------ does not have a uniform texture
homogeneous ------ used in the sense of having a uniform texture
hyperechoic ------ a region containing many echoes, used mainly to describe an area in relation to its surrounding structures
hypoechoic ------ a region that contains only a few echoes, used maily to descrie a area in relation to its surrounding structures
interface ------ surface forming the boundary between different structures
isoechoic ------ of the same echogenicity as a neighboring area, but not necessarily of the same texture
parenchyma ------ 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
rocking ------ holding the transducer in one spot and angling along the curve or rounded protion of the scan head
rotating ------ twisting the transducer in a circular motion while holding it in one place
sector ------ shape of the image on the film, depends on the type of transducer that is used
shadowing ------ failure of the sound beam to pass through an object, causing the absense of echoes posterior
solid ------ defines a mass with no fluid areas
transducer ------ a device capable of convering energy from one form to another
ultrasound ------ sound waves which have a frequency above the audible range of the human ear
