ALARA (As Low As Reasonably Achievable) principle.
However, not all examinations can be performed with an
extremely low level of acoustic energy. Controlling the
acoustic level at an extremely low level leads to low-quality
images or insufficient Doppler signals, adversely affecting the
reliability of the diagnosis. However, increasing the acoustic
power more than necessary does not always contribute to an
increase in quality of information required for diagnosis,
rather increasing the risk of generating bioeffects.
Users must take responsibility for the safety of patients and
utilize ultrasound deliberately. Deliberate use of ultrasound
