2D-Mode and M-Mode Imaging Controls
Use the imaging controls to activate an operating mode, change the image
orientation, or modify the sweep display.
2D
A dual-function control that activates one function when the control is
pressed and another function when the control is rotated.
Pressing the 2D control activates 2D-mode for grayscale imaging. If a mixed
mode or imaging function is active, pressing 2D causes the system to exit
the mode or function and return to 2D-mode.
Rotating the 2D control changes the overall gain for 2D-mode. Rotating the
2D control clockwise increases the gain; a counterclockwise rotation
decreases the gain.
The range for gain settings is from 0 dB to 40 dB. When combined with the
DGC controls, a gain range of –15 dB to 55 dB is possible.
B: 55/ 1/
32
Gain (dB) is indicated by the shaded value.
The gain value displays as the third number in the Image Parameter area for
2D-mode, at the bottom of the image screen.
Split
Creates side-by-side images from one 2D-mode image. The two images are
simultaneously frozen or real-time.
Certain post-processing imaging parameters can be changed in the right
image, allowing you to compare the effects of different image settings on an
anatomical structure.
