UPDATE 2026
Propagation repetition period (PRP) and depth are _____ related - (answer)directly
Pulse repetition frequency (PRF) and depth are _____ related - (answer)inversely
7 components of the imaging transducer - (answer)
At what portion of the beam is the focus located on - (answer)the narrowest portion
Define axial resolution and the direction the beams travel - (answer)Identifies 2 structures that are on
top of and below one another; the beam travels parallel
Define lateral resolution and the direction the beams travel - (answer)Identifies 2 structures that are
side by side; the beam travels perpendicular
What are the 3 display modes - (answer)-Amplitude mode
-Brightness mode
-Motion mode
Relationship between time of flight and sound pulse travel - (answer)Directly related
How many transducer characteristics are there? - (answer)5
Huygens' principle - (answer)Explains why the soundbeam has an hourglass shape
Characteristics that determine the frequency of sound - (answer)Speed of sound and thickness of PZT
elements

UPDATE 2026
Apodization defined - (answer)reduces the strength of the side grating lobes
Purpose of matching layer on a transducer - (answer)aids in the transmission of sound waves into the
skin
Factors that determine beam divergence - (answer)1. transducer diameter
2. frequency of the sound
Side/grating lobes and lateral resolution relationship - (answer)Inversely related; side lobes degrade
resolution
Linear probe is used in which ultrasound modality - (answer)Vascular
13 microsecond rule and relationship to tissue depth - (answer)A sound wave travels 1cm in depth every
13ms
Vector array images have a ____ image shape - (answer)Trapezoid
