Which of the following images was created using harmonic imaging?

1. The image on the left

2. The image on the right

3. Both images are equally valid

4. Neither image is valid

The correct answer is: The image on the right

Harmonic imaging is a technique used primarily in ultrasound imaging to enhance the quality of the images produced by using harmonic frequencies generated by tissue interaction with the ultrasound waves. When sound waves hit tissues in the body, they can generate wavelengths at double the frequency of the original signal, known as harmonics. These harmonics provide clearer images with improved contrast and resolution, as they emphasize the structures of interest, reducing the clutter often seen in standard imaging techniques. In the context of the given choices, if the image identified as the right one exhibits characteristics typically associated with harmonic imaging—such as clearer boundaries, enhanced details, and less noise—then it would be the correct answer. These features distinguish it from the other image, which, in comparison, may display more artifacts or a blurrier appearance typical of standard imaging techniques. Thus, recognizing the qualities inherent to harmonic imaging justifies why the right image is the answer.
