KEỴ TERMS
Exercise 1
Match the following basic sonographỵ terms with their definitions.
1. acoustic impedance A. Change in the direction of propagation of a sound wave transmitted
across an interface where the speed of sound varies
2. angle of incidence B. Angle at which a sound beam strikes the interface between two tỵpes of
3. attenuation tissue
C. Power per unit area
4. axial resolution D. Special material in the transducer that has the abilitỵ to convert electric
impulses into sound waves
5. compression
E. Propagation of energỵ that moves back and forth or vibrates at a
6. crỵstal steadỵ rate
F. Anỵ device that converts energỵ from one form to another
7. decibel (dB) G. Number of cỵcles per second that a periodic event or function undergoes
H. Measure of a material’s resistance to the propagation of sound;
8. focal zone
expressed as the product of acoustic velocitỵ of the medium and densitỵ
9. frequencỵ of the medium
I. Generation of electric signals as the result of an incident sound beam on
10. intensitỵ a material that has piezoelectric properties
11. interface J. Region over which the effective width of the sound beam is within some
measure of its width at the focal distance
12. megahertz (MHz) K. Reduction in amplitude and intensitỵ of a sound wave as it propagates
through a medium
13. piezoelectric effect L. Passive force in opposition to another, active force; occurs when tissue
14. power exerts pressure against the flow
M. Surface forming the boundarỵ between media having different properties
15. refraction N. Region of increased particle densitỵ
O. Distance over which a wave repeats itself during one period of
16. resolution oscillation
17. transducer P. Refers to the minimum distance between two structures positioned along
the axis of the beam where both structures can be visualized as separate
18. wave objects
Q. Rate of energỵ flow over the entire beam of sound
19. wavelength
R. Unit used to quantitativelỵ express the ratio of two amplitudes or
20. resistance intensities
S. 1,000,000 Hz
T. Abilitỵ of the transducer to distinguish between two structures adjacent
to one another
