What is the core objective of ALARA in imaging?

• A. To maximize image resolution at any cost
• B. To standardize protocols regardless of dose
• C. To obtain the lowest radiation dose possible by following safety procedures
• D. To minimize equipment usage

Answer: (C)

ALARA in imaging means keeping radiation exposure as low as reasonably achievable while still obtaining diagnostically useful images. This is done by following safety procedures and using dose-reduction strategies such as choosing the minimum exposure factors appropriate for the patient, applying shielding and proper collimation, utilizing dose-saving features like automatic exposure control, minimizing repeats, and keeping imaging time as short as possible. The aim is to balance image quality with patient safety, not to maximize resolution at any cost, not to standardize protocols without considering dose, and not to minimize equipment use.
