How can the use of a technique chart reduce dose creep in a DR program?

• A. It standardizes starting exposure factors by exam and patient size, reducing the temptation to overexpose to achieve brightness.
• B. It automatically increases brightness for all exams.
• C. It eliminates the need for follow-up QA.
• D. It reduces image quality.

Answer: (A)

A technique chart provides standardized starting exposure factors for each exam type and patient size, giving you a sensible baseline to obtain a quality image without overdoing the dose. In digital radiography, displays and post-processing can mask underexposure, which tempts operators to push exposure higher to make the image look brighter. With a chart, you start from vetted, appropriate values for the patient and exam, so adjustments are small and justification-based rather than habit-driven. If an image isn’t at the target brightness, you adjust using the chart’s guidance rather than cranking up exposure across the board, which helps prevent gradual, cumulative dose increases over time. This consistency supports dose optimization and makes it easier to track and compare exposures, keeping patient dose as low as reasonably achievable while maintaining image quality.
