Preparations
You may use a phantom (optional) when doing these tests.
1.) Connect one of the probes, to the scanner’s active probe connector.

- For available probes, Section 9-13 "Probes" on page 9-24.

Adjustments" on page 6-2).
4.) Press B-MODE on the Operator Panel to access B-Mode.
5.) These Image Controls are used to optimize the B-Mode 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 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.
Checks
• Check Width, Frame rate, Frequency. The results of these adjustments must be verified on the
B-Mode sector on the screen.
• Check Up/Down, Left/Right, B Color Maps and Cineloop. The results of these adjustments must be
verified on the B-Mode sector on the screen.
• Check Gain, TGC and Depth.
