How do you select the primary factors? What do you need to consult?

• A. The Exposure Index
• B. The Technique Chart
• C. The Film-Screen Speed
• D. The Patient's Age

Answer: (B)

Consulting the technique chart is how you pick the primary factors. The chart provides the recommended combinations of kVp and mA (and exposure time when needed) for different body parts and patient sizes on your specific equipment. It standardizes technique, helps you achieve consistent receptor exposure and image quality, and keeps patient dose in check. After exposure, you can use the exposure index to verify results. The other items play a role in understanding exposure quality or adjusting for special scenarios, but they’re not the primary guide for selecting the initial factors.
