What is the purpose of ALARA in imaging?

ALARA means keeping radiation exposure as low as reasonably achievable while still obtaining a diagnostically useful image. The purpose is to protect patients and staff by balancing the need for image quality with the goal of minimizing dose. In practice, that means using the lowest exposure factors that still produce a readable image, applying shielding and collimation to limit the beam, maximizing distance when possible, avoiding repeat exams, and choosing alternative, non-radiation or lower-dose modalities when appropriate. It’s not about maximizing image quality at any dose, avoiding imaging altogether, or increasing exposure—it's about optimizing dose to get the necessary information with the smallest risk.
