Viewing and Image Transformation Tools¶
Select/Move Item Tool (Default)¶

The Default
tool (similar to the tool in the simple viewer) allows users to change the position of the images loaded in the views, move and rotate the slicers, 3D volume and CMPR path points,
as well as modify existing measurements on the scene. The right mouse button is assigned to this tool by default.
Rotation¶

Use the rotation dialog to rotate, flip and mirror images in the active MPR viewport. More information about how to use the rotation dialog can be found here.
Hide/Show Labels and Measurements¶
The CT Viewer offers three different options to manipulate the visibility of labels and measurements on the scene.

All labels related to every measurement are hidden. The measurements remain visible on all viewports.
Toggle between the all three states by pressing the Hide/Show Labels and Measurements
button multiple times.
The icon of the button represents the active state in the CT Viewer. When either the labels or both labels and measurements are hidden, the button is toggled on.
Show/Hide List of Measurements¶

The measurement list is an independent window displaying all of the measurements drawn in all MPR viewports. Press the Measurement List
button in the left toolbar to open the window. The window will be automatically closed
when closing the CT Viewer. Users can continue working in the VisioVIEW CT Viewer even though the list is opened in the background.
Each measurement in all MPR viewports is represented as a separate entry into the measurement list. All measurements contain the following information:
Color: The color of the measurement shape drawn on the scene.
View Box: The specific MPR plane this measurement was drawn in.
Active: Whether the specific slice which the measurement was drawn on is currently visible (active) in the viewport.
Type: The type of the measurement.
Value: Specific parameters describing the measurement (dimension, area, average, minimum and maximum HU values inscribed with the measurement).
At the bottom of the measurement list window, there are four separate buttons indicating various different actions with the measurements.
Show Measurement: Quickly and easily locate the specific slice that contains the selected measurement. The selected measurement will become active.
Delete Selected: Delete the selected measurement from the image.
Delete All Planar Measurements: Delete all planar measurements (drawn on the three standard MPR planes) from the images.
Delete All CMPR Measurements: Delete all measurements drawn on the CMPR slices.
