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 control to optimize imaging in the blood flow regions and make a cleaner, less noisy
image.
Use Reject controls to reduce noise in the image.
