Step Task Expected Results
1
2D Mode Gain
Rotate the
2D MODE key to adjust the sensitivity (brightness) of the entire
image.
2
Transmit Power
Optimizes image quality and allows user to reduce beam intensity.
3
Depth
Adjusts the depth range of the ultrasound image for the region of interest.
The number of image lines and the frame rate are automatically optimized.
4
Screen Format (Dual, Quad, Single)
Press this keys to change the display Mode from Single to DUAL or QUAD
display mode.
Press the
SINGLE format key or the 2D MODE key to change from Dual or
Quad to Single display.

XBEAM-CRI
* (CrossBeam
Compound Resolution Imaging)
Pulses are transmitted not only perpendicularly to the acoustic window, but
also in oblique directions. The advantages of XBeam-CRI are enhanced
contrast resolution with better tissue differentiation and clear organ borders.
