What is the effect of setting the system gain to its maximum?

Explanation:
System gain is the amplification applied to the received echoes to make the image brighter. It does not change the energy emitted into the tissue. Tissue heating, cavitation, and fluid particle streaming depend on the transmitted acoustic power and exposure, not on how strong the receiver signal is amplified. So maximum gain won’t increase heating, cavitation risk, or streaming; it only affects image brightness. None of the listed effects occur from setting the system gain to maximum.
