Dose optimization

Definition

Dose optimization is the process of determining the most effective and safe amount of radiation to be used during medical imaging procedures, such as computed tomography (CT) scans. This approach aims to balance image quality with radiation exposure to minimize risks while ensuring accurate diagnostic results. By refining the dose used in imaging, healthcare providers can enhance patient safety and improve outcomes.
