Ultrasound System  The Electronic Device & Transducer  System is
changed by?  Selecting a different transducer  What parameters
of sound can't be adjusted w/o changing the system?  Frequency &
Wavelength  What 4 factors can be changed  PRP, Duty Factor,
Listening Time, Amplitude  What is a graph?  A diagram
representing data and relationships between data  Horizontal
Axis   Vertical Axis   What is related?  Relationship between
two items i.e Transducer Frequency and Depth  High Frequency
attenuates?   What is unrelated?  Absence of a relationship
between two items.  Why are Frequency and propagation speed
unrelated?  Speed is controlled by the medium. Frequency is
controlled by crystal thickness.  2 factors that affect
propagation speed  Density and Stiffness  Thin crystal  High
frequency  Thick crystal  Low frequency  Directly Related  When
one item increases, the other also increases.  Crystal Diameter
and Focal Length  Directly Related  Frequenc
