The orientation help image is only displayed in the lower right quadrant in
Sectional Planes mode.
To activate or deactivate the O.H. Graphic select the [Orient Help] key in the
Sectional Planes mode.
The help image figure shows the intersections of a plane within the volume
body by lines as a section plane.
e.g.: O.H Graphic of an Abdominal Transducer.
The alignment of the volume box is NOT the alignment of the patient's body.
This function will optimize the contrast resolution of the sectional planes (A, B and C)
according to the histogram of the scan area. However, the rendered image is NOT affected.
The primary result is a value for the upper and lower endpoint of the actual histogram.
Pressing the [auto] key causes automatic optimization of the gray scale to enhance the
contrast resolution of the sectional planes (A, B and C). When the key is pressed again, the
optimization according to the histogram will be updated and remain active.
Double-click the [auto] key to switch off the Automatic Optimization.
Remarks:
•
When the Automatic Optimization function is active, the [auto] key is illuminated green.
•
The rendered image is NOT affected (not optimized).
Choosing a reference image automatically determines the rotary controls (mode buttons) and
the trackball for the adjustment of a sectional plane. With simultaneous display of the sectional
planes A, B and C the one chosen for reference is marked by the lit responsible key (e.g., A)
If a single sectional plane A, B or C is displayed (full-screen mode), this is the reference
image. The reference image may be changed by selecting the buttons A, B, or C.
