What information do technique charts indicate?

• A. The Speed of Film or Digital Receptor, Patient Size, and Technique Factors (kVp, mA, and Time)
• B. The Fastest Film Speed Available
• C. Recommended Patient Appointment Times
• D. Maintenance Schedule

Answer: (A)

Technique charts guide how to choose exposure settings by tying together three pieces of information: the speed of the film or digital receptor (how sensitive the receptor is to x‑rays), the patient’s size (which affects how much the x‑ray beam is attenuated), and the exposure factors themselves (kVp, mA, and time). This combination lets you predict the appropriate exposure to achieve consistent image density and contrast while minimizing dose. The other options don’t fit because they address only one aspect or irrelevant topics—fastest film speed alone doesn’t account for patient size or actual exposure settings, appointment times are unrelated to imaging exposure, and maintenance schedules aren’t about how to set exposures.
