Which adjustment follows the ALARA (As Low As Reasonably Achievable) principle of patient safety?

The ALARA principle stands for "As Low As Reasonably Achievable" and aims to minimize patient exposure to ultrasound energy. Decreasing the output power reduces the intensity of the ultrasound waves, thereby reducing the potential for tissue heating and mechanical effects, which aligns with the ALARA principle of minimizing exposure while still obtaining necessary diagnostic information.
