Gain in general imaging ultrasound refers to the amplification of returning echoes. It directly controls the brightness of the overall ultrasound image without affecting the acoustic output. Adjusting gain allows sonographers to optimize image visibility, highlighting subtle tissue differences and improving diagnostic accuracy. Proper gain settings are essential for clear, detailed imaging and avoiding artifacts. Mastering gain is crucial for effective ultrasound interpretation.
