What safety principles apply to sonography?

The principle of ALARA, which stands for "As Low As Reasonably Achievable," is fundamental in the field of medical imaging, including sonography. This principle emphasizes the importance of minimizing patient exposure to ultrasound energy while still obtaining clinically useful diagnostic information. It encourages sonographers to use the lowest possible intensity and duration of ultrasound that will allow for effective imaging, thereby reducing the risk of potential biological effects on patients. By adhering to the ALARA principle, practitioners ensure they are taking necessary precautions to protect patients and maintain safety standards during sonographic procedures.

In the context of sonography, the ALARA principle involves careful consideration of settings such as output power, duration of the exam, and the overall approach taken to achieve the required diagnostic information while safeguarding patient health. This principle reinforces the ethical responsibility of healthcare providers to prioritize patient safety throughout the imaging process.
