Start situation
The position of the volume body in relation to the display plane is determined by a relative coordinate
system. This is made up of three orthogonal axes, the common intersection of which is the 3-axial
center of rotation. These axes are displayed within the display plane - exactly in the
X-, Y- and Z-directions and colored. Rotation about any of these axes and displacement of the center
of rotation make any imaginable plane within the volume body displayable. The INIT position of the
volume body in relation to the display plane is resetable; it is the start situation after completion of a
volume scan.
The standard representation: 3 sections mode
The 3 orthogonal sectional planes are simultaneously displayed on the quartered screen field of the
monitor. Each quarter field displays a sectional view through the volume body as shown below.
Sectional planes A, B, C
The intersection lines of the planes are displayed in colors:
AB = blue AC = red
Orientation of intersection lines on the screen:
Section/field
Intersection line AB
Intersection line AC
Intersection line BC
By this definition the relation of the position of the 3 images A, B, C is also defined (as made clear by
the direction of arrows).
The presentation of 3 orthogonal sectional planes may lead to non-conformance with the conventional
customized orientation to the patient in 2D sonography. An identification system - the automatic
display of the direction of section - will clarify.
Please note: Whenever a usual longitudinal section (of the patient) is selected for display field A,
the usual orientation for longitudinal and transverse sections is valid.
