5.) These Image Controls are used to optimize the 2D picture:
-Use Gain and TGC controls to optimize the overall image together with the Power control.
-Use Depth to adjust the range to be imaged.
-Use Focus to center the focal point(s) around the region of interest.
-Use Frequency (move to higher frequencies) or Frame rate (move to lower frame rate) to
increase resolution in image.
-Use Frequency (move to lower frequency) to increase penetration.
-Use the DDP control to optimize imaging in the blood flow regions and make a cleaner, less
noisy image.
-Use Reject/Adaptive Reject controls to reduce noise in the image.
-Use the UD Clarity control to personalized appearance of the tissue. Moving the paddle to
the left creates a smoother image, though keeping boundaries sharp. Moving the paddle to
the right creates a crisper image.
