Threshold Control In Gray Render Mode; Transparency In Gray Render Mode - GE VOLUSON 730Pro Basic User Manual

X-Ray Mode:
The software module allows selection of 2 modes which are simultaneously calculated. Always the
actual selected mode is displayed with 100%. With the [Mix]-key one can mix between the chosen
modes. Selection itself is liberal, except the Light mode, which combines only with Surface display.

Threshold Control in Gray Render Mode

Function of the threshold values (Surface Mode only)
In the event Surface mode is selected, it will normally be necessary to adjust the low threshold for the
border recognition of the surface. These threshold values do not apply for the Transparent modes!
Threshold Low (Reject):
By changing the [TH.low] all echoes below the level are enhanced in pink color for a certain interval.
Application: With this function small echoes or noise are removed, to have a "clear sight" from the
start boarder of the render box to the desired Surface.

Transparency in Gray Render Mode

small number = low transparency
A higher number makes the gray scale information more transparent.
Note: The control for the Transparency is found in the status area.
