The B Mode is the system's default mode.
•
Connect one of the probes.
•
Turn ON the scanner.
The B Mode is displayed (default mode).
Press B on the Operator Panel to access B mode.
These Image Controls are used to optimize the B Mode 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. Red. (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.
