5-38 Image Optimization
ROI size and position
Roll the trackball to change the ROI size and position, press the <Set> key to toggle
between setting the size (dotted line) and position (solid line).
Curved VOI adjustment
Roll the trackball to change the curved VOI position, press the <Set> key to switch among
the state of changing ROI and curved VOI.
This function is to change the curved shape of the nearest VOI section, to facilitate
observation for the interested volume data.
It can be adjusted both in acquisition preparation status, and in A, B, C sections of review/
4D imaging status, while a triangle of control point on the curved VOI is displayed.
Depending on the view direction, the orientation and the shape (line or dot) of curved VOI
vary:
At the upper part of curved VOI
At the lower part of curved VOI
At the left part of curved VOI
At the right part of curved VOI
About the probes
A 2D imaging probe can be applied for Smart 3D imaging, however, to realize Static 3D
imaging, 4D imaging, STIC, iPage, SCV, CMPR, Color 3D or Niche, a volume probe should be
selected.
MPR
The principle of 3D imaging is to render a 3D image from multiple 2D image information. The
following describes the spatial relation of 3 MPRs (A, B and C) and the 3D image (VR).
In the quad display format view, the screen displays 3 MPRs (A, B and C) and the 3D image.
