The choice to modify the frequency of the ultrasound waves is a valid approach for enhancing the quality of an ultrasound image. Different frequencies have distinct penetration and resolution qualities. Higher frequency ultrasound waves provide better resolution and detail, which is particularly beneficial when imaging superficial structures. However, they have limited penetration capability. Conversely, lower frequency waves penetrate deeper into tissues but usually result in images with lower resolution. By selecting an appropriate frequency for the specific imaging requirements, a sonographer can optimize image quality according to the anatomical area being examined and the depth of the structures involved.

Adjusting the patient's position can improve visibility of certain structures but may not inherently enhance the overall image quality across the board. Using additional imaging software can also aid in processing and analyzing images but may not be directly related to the generation of the ultrasound data itself. Lastly, using less gel can negatively impact image quality since the gel serves as a coupling agent to reduce air between the transducer and the skin, which is necessary for effective transmission of sound waves.
