Question
Which of the following describes what the frequency of an ultrasound transducer is best? The amount of time over which one cycle takes place A representation of how compressed tissue becomes when encountering a sound wave How frequently the ultrasound unit sends out a pulse. The speed at which a sound wave moves through tissue
Solution
The frequency of an ultrasound transducer is best described as "How frequently the ultrasound unit sends out a pulse."
Here's why:
-
The frequency of an ultrasound transducer refers to the number of cycles of a wave that pass a certain point in a specified amount of time. In the context of an ultrasound machine, this is the number of sound waves that are sent out by the transducer in one second.
-
The amount of time over which one cycle takes place is related to frequency, but it is not the best description. This is actually the period of the wave, which is the reciprocal of the frequency.
-
A representation of how compressed tissue becomes when encountering a sound wave is more related to the amplitude of the wave, not its frequency.
-
The speed at which a sound wave moves through tissue is the speed of sound in that particular medium, not the frequency of the ultrasound transducer. The speed of sound in a medium is determined by the properties of the medium, not the properties of the wave.
