Which action is not typically performed by the sonographer?

• A. Clean VCR Recording Heads
• B. Adjust Overall Gain
• C. Clean Pixels
• D. Adjust TGC

Answer: (C)

Focusing on how to obtain a diagnostic image, a sonographer routinely tweaks image brightness and balance to make structures visible. Adjusting the overall gain is a fundamental step because it controls the overall amplification of returning echoes, ensuring the image isn’t too dark or washed out. Time Gain Compensation is another core adjustment, allowing you to compensate for the natural attenuation of sound with depth so that near and far tissues display a consistent brightness. Maintenance tasks like cleaning the VCR recording heads are outside the scanning duties and handled by service or biomedical staff to keep equipment functioning properly. Cleaning pixels, however, isn’t a manual task performed by the sonographer during an exam; any pixel-level cleanup or despeckling is typically done by the machine’s image processing software rather than as a hands-on action during scanning. For these reasons, cleaning pixels is not a routine sonographer duty, making it the best choice.
