Step Task Expected Results
1
2D Mode Gain
Rotate the ACTIVE MODE
rotary control to adjust the sensitivity (brightness)
of the entire image.
2
Transmit Power
Optimizes image quality and allows user to reduce/increase beam intensity.
3
Penetration 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

6
2D Automatic Optimization
Pressing the AUTO key causes automatic optimization of the gray scale to
enhance the contrast resolution.
Pressing again: optimization will be updated and remain active.
Press the AUTO
key twice to switch off the Automatic Optimization in 2D.
7
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.
