Which item is not listed among the six direct factors influencing X-ray personnel performance?

• A. Proper collimation
• B. Correct patient positioning
• C. Use of computer-assisted image processing
• D. Proper film handling and processing

Answer: (C)

The main idea is about actions you directly perform during the radiographic process that directly influence image quality and patient safety. Proper collimation and correct patient positioning are fundamental hands-on controls you apply at the moment of imaging to limit irradiation to the area of interest and ensure the anatomy is captured accurately. Proper film handling and processing are also direct actions that affect whether the image is free of artifacts and develops correctly.

Use of computer-assisted image processing, while helpful for post-processing and analysis, occurs after the exposure and development steps. It’s a software aid rather than a technique you perform during image acquisition, so it isn’t considered one of the direct factors governing the radiograph obtained.
