What is not the responsibility of the sonographer?

• A. Clean the Filters
• B. Adjust the Recorder
• C. Adjust the Converter Matrix
• D. Change Paper

Answer: (C)

In this field, day-to-day duties focus on obtaining and recording good images and keeping the workflow smooth, while major hardware or software adjustments that affect how signals are converted to images are handled by service engineers, not the operator. The converter matrix is a part of the machine’s internal signal processing that maps raw electrical signals into the final image. Changing it would alter how all images are formed and requires specialized calibration and access; it’s not something a sonographer should adjust during routine exams.

The other tasks align with routine operation: cleaning the filters helps keep the signal path clean and prevents artifacts, ensuring the recorder is functioning allows you to document and review studies, and changing paper maintains the ability to produce hard copies when needed. These are practical, day-to-day responsibilities that support imaging quality and documentation.
