During a renal ultrasound, the sonographer finds it necessary to adjust controls on the ultrasound system to improve the image. What CANNOT be adjusted by the operator?

  1. Amplitude

  2. Frequency

  3. Output power

  4. Speed

The correct answer is: Speed

During a renal ultrasound, the sonographer can adjust the amplitude, frequency, and output power to improve the image quality. Amplitude refers to the strength of the sound wave, frequency is the number of sound waves produced per second, and output power controls the intensity of the sound beam. These are parameters that the operator can adjust to optimize the image. However, speed is not a parameter that can be adjusted by the operator during an ultrasound exam. The speed setting typically refers to how fast the sound waves travel through the tissues, and this is a fixed setting that is not typically variable during a scan.
