Answer 1

The Gain control on the US machine should be adjusted to adjust the brightness of the US image.

Step-by-step explanation:

To adjust the brightness of the US image, the Gain control on the US machine should be adjusted.

The Gain control alters the intensity of the echoes received during ultrasound imaging, which affects the brightness of the image.

By increasing the Gain, the echoes are amplified, resulting in a brighter image.
