- The concept of ALARA (As Low As Reasonably Achievable) is fundamental in minimizing patient exposure because it emphasizes reducing radiation doses to the lowest possible level while still achieving the necessary diagnostic quality.
- It promotes a continuous effort to optimize procedures, balancing risk and benefit.
- Unlike fixed limits, ALARA is a proactive approach to radiation safety that guides technologists and clinicians in daily practice to protect patients from unnecessary radiation.
- This principle is widely adopted as the cornerstone of radiation protection in medical imaging.
