Approximately what percentage of radiographic technique chart cases require minor adjustments?

• A. 5
• B. 10-25
• C. 25-50
• D. 75

Answer: (B)

When a radiographic technique chart is used, it provides baseline exposure factors to produce consistent images. In routine practice, most exams align with those chart values, and only a minority need small tweaks to account for differences in patient size, anatomy, or technique variability.

That’s why 10-25% is the best pick: it reflects the typical rate of minor adjustments—small changes to exposure factors after reviewing the image—while the majority of cases fit the chart or require only light fine-tuning. A rate around 5% would understate how often small refinements are needed, and rates like 25-50% or 75% suggest more frequent or major changes that aren’t common with standard technique charts.
