◉ What is the result of mechanical energy that produces alternating
compression and rarefaction of the conducting medium as it travels
as a wave?
Answer: Sound
◉ Unit of frequency, equal to 1 cycle per second
Answer: Hertz
◉ Region of increased particle density
Answer: Compression
◉ Change in the direction of propagation of a sound wave
transmitted across an interface where the speed of sound varies
Answer: Rarefaction
◉ Propagation of energy that moves back and forth or vibrates at a
steady rate
Answer: Wave
,◉ Ultrasound uses short sound pulses at frequencies of ____ to ______
million cycles/sec (MHz) that are transmitted into the body to
examine soft tissue anatomic structures
Answer: 1 to 20
◉ Generation of electric signals as a result of an incident sound
beam on a material that has these properties
Answer: Piezoelectric effect
◉ The _________ converts electrical energy into mechanical energy as
the sonographic image is produced
Answer: Transducer
◉ The rate and direction at which sound propagates through a
medium; the average velocity of sound in soft tissues is 1540m/sec
Answer: Velocity
◉ What determines how fast sound waves will travel through the
structure?
Answer: Stiffness and density
◉ The more closely packed the molecules, the __________ is the speed
of sound.
, Answer: Faster
◉ Sound waves travel faster or slower through gas (air)?
Answer: Slower
◉ Unit used to quantitively express the ratio of two amplitudes or
intensities
Answer: Decibel (dB)
◉ Used to measure the intensity (strength), Amplitude, and power
of an ultrasound wave
Answer: Decibel (dB)
◉ Strength of the ultrasound wave measured in decibels
Answer: Amplitude
◉ Rate of energy flow over the entire beam of sound or transmitted,
measured in Watts (W) or milliwatts (mW)
Answer: Power
◉ Power per unit area
Answer: Intensity
