Examine the ultrasound image when you make any fine adjustment of the gain. (1)

(2)

(3)

a) TOTAL Gain (1) Sets the echo sensitivity of the overall image. (Adjustment range: 20 – 80 dB) b) DYNAMIC RANGE (2) Adjusts the dynamic range of the image. (Adjustment range: 30 – 70 dB) A higher dynamic range makes the black and white contrast weaker. A lower dynamic range makes the black and white contrast stronger and creates a high contrast image. c) Near Gain (3) Sets the echo reflection sensitivity in the neighborhood of the anterior eye and vitreous.
