Which of the following choices determines the signal amplitude in the transducer of an ultrasound? MCQ Options: Option 1: Frequency of the transmitted ultrasound wave Option 2: Speed of sound in the medium Option 3: Reflector depth Option 4: Size of the transducer crystal

Answer :

The signal amplitude in the transducer of an ultrasound is determined by the size of the transducer crystal.The signal amplitude in the transducer of an ultrasound is not determined by the Frequency of the transmitted ultrasound wave, Speed of sound in the medium, or reflector depth. The amplitude of the signal, which is the maximum displacement of a wave from its average position, is primarily determined by the size of the transducer crystal.

When a transducer receives an ultrasound wave, it converts the energy into an electrical signal. The larger the crystal in the transducer, the more energy it can convert, leading to a higher amplitude signal.
