What is the purpose of a technique chart?

• A. To standardize technique selections for body parts and patient sizes
• B. To schedule patient appointments
• C. To calibrate detectors
• D. To measure patient dose

Answer: (A)

Technique charts standardize exposure choices for different body parts and patient sizes, guiding technologists to select the appropriate exposure factors for each situation. By translating patient thickness and anatomy into a recommended combination of kVp and mAs (and sometimes other factors), the chart helps achieve consistent image quality while keeping patient dose as low as reasonably achievable. It also reduces guesswork and repeats, speeding up exams and improving overall safety and quality. The other options don’t describe how a technique chart functions: scheduling is administrative, detector calibration is a separate QC task, and measuring patient dose involves dosimetry rather than choosing exposure factors.
