8.3.2.1 CF Box Position and CF Box Size
In 2D imaging the relationship between 2D frame rate, line density, and field-of-view are well
known factors to be considered to obtain optimum 2D images. Similar relationships exist in
Color imaging. On the CF Submenu the selection of the Quality adjusts the balance between
the 2D Line Density and the Color mode line density. The values available are scan head-
dependent.
The ability to change the CF box size and position provides flexibility in CF imaging. The
trackball changes the CF box size and position.
Adjust the CF box position on the 2D image with the trackball (in Single, Dual, or Quad mode).
← → CF box horizontal position
↑ ↓ CF box vertical position
The box is adjustable within the entire 2D image area.
The upper trackball key changes between CF box position and CF box size and vice versa.
↑ decrease the vertical CF box size ↓ increase the vertical CF box size
→ increase the horizontal CF box size ← decrease the horizontal CF box size
