How is dose tracking integrated into digital radiography systems?

• A. Dose tracking is manual and not integrated.
• B. DR systems do not track dose.
• C. Dose tracking replaces all QA testing.
• D. Exposure data (kVp, mA, time) and dose metrics (DAP/EI) are recorded and compiled for patient dose tracking and QA analysis.

Answer: (D)

Dose tracking in digital radiography is built in by automatically capturing the exposure factors and dose metrics of each exam. The system records the technical exposure data (kVp, mA, and exposure time) along with dose indicators such as Dose Area Product (DAP) and, in many systems, Exposure Index (EI). This information is stored with the image data (often in a DICOM Radiation Dose Structured Report) and compiled into a patient dose record. This enables ongoing patient dose tracking across studies and supports QA analysis, benchmarking, and alerts when doses exceed reference values. It’s automatic and integrated, rather than manual, and it complements but does not replace QA testing.
