What is the name of the frequency used in tissue harmonics that is responsible for image production?

Overall gain
Fundamental frequency
Harmonic frequency
Spatial compounding

The correct answer is: Fundamental frequency

The frequency used in tissue harmonics that is responsible for image production is known as the fundamental frequency. This is because tissue harmonics creates a second harmonic signal by using sound waves at twice the frequency of the original signal, which results in a clearer and more precise image. Options A, C, and D are incorrect because they do not accurately describe the frequency used in tissue harmonics. Overall gain refers to the amplification of the signal, harmonic frequency refers to a multiple of the original frequency, and spatial compounding is a technique used to combine multiple images for a better final image.
