Table 5-9: Easy 3D Description and Instructions for Use
3D Parameter Description
Reset Resets the 3D volume of interest back to its original orientation.
Utilities Select Average Off, Average Light, Average Medium, or Average Strong.
Undo Undoes any manipulation you have done to your 3D dataset.
Auto Movie Initializes the calculation and display of a 3D movie. A rotation of 30 degrees left and
right around the actual image position (either the default position after acquisition or
the position that was manually defined by manipulating the 3D volume of interest) is
shown. For this 60 degree rotation, eleven images in steps of 6 degrees are
calculated.
Scalpel Structures, for example a part of the placenta hiding the view to a fetal face, can be
cut out in a rendered image. All visible structures can be cut out.
The option of ‘erase inside’ deletes all structures inside the marked region. The option
of ‘erase outside’ deletes all structures outside the marked region.
The region in the rendered image is marked with the right Set key. To define the
contour of the region, press the right Set key for each vertex. To close the contour,
double click the right Set key. As long as a contour is not closed, it can be traced back
with the left Set key. The cut out process can be undone by the Undo Last function.
As soon as the Apply button is pressed, a new dataset is generated.
Gray Surface Activates the gray surface rendering mode. It leads to a transparent appearance of
the object, generated by displaying only a surrounding shell of structures.
