The 2D Mode is the system's default mode.
• Connect one of the probes.
• Turn ON the scanner.
The 2D Mode is displayed (default mode).
Press 2D on the Operator Panel to access 2D mode.
These Image Controls are used to optimize the 2D picture.
Verify that all the listed controls are working as intended:
• 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 Reject control to reduce noise in the image.
• Use the DDP control to optimize imaging in the blood flow
regions and make a cleaner, less noisy image.
• Use UD Clarity (Cardiac) or UD Sp. Re. (non-cardiac) to
reduce image speckle. Extra care must be taken to select
the optimal Speckle reduction level, as too much filtering of
speckle can mask or obscure desired image detail.
• Use Adaptive reject (Cardiac) to reduce near field haze
and blood pol artifact without diluting tissue appearance of
moving structures.
