Description
Deposits an arrow on the screen. Click and drag the end of the arrow to re-size and rotate it. Click and
drag anywhere on the arrow to move it.
Deposits a point on the viewports to display a RAS coordinate and vector ROI at the current cursor posi‐
tion.
Displays statistics as average, minimum and maximum voxel values, standard deviation, and area within
the 2D ROI.
Displays statistics as average, minimum and maximum voxel values, standard deviation, and volume
within the 3D ROI.
The 3D color ROI provides the ability to colorize voxels inside the ROI based on ranges of voxel value.
Additional Statistics such as volume can be calculated for each colored area.
(Click the arrow in the lower-right corner of the button to select the 3D Box ROI, the 3D Color ROI, or the
Spherical ROI.)
Opens the Annotate control panel, which allows you to use predefined annotations on the views or create
new annotation.
Many of the options are linked to measurement tools. For example, the Distance Annotation allows you to
link an annotation with a measurement (e.g., Stenosis: xx.x mm).
Opens the Preset Annotation control panel, which allows you to place preset annotations on an image.
Opens the Measure Distance control panel, which allows you to perform measurements on an image.
Opens the 2D Angle control panel, which allows you to deposit thee points on an image.
Opens the Area control panel, which allows you to deposit points around a region of interest. Right-click
to convert to ROI or display results.
Opens the Volume control panel, which allows you to deposit a point to obtain a volume measurement.
Opens the Set Color control panel, which allows selection of a color map or custom color to apply to non-
VR viewports.
Opens the Trace control panel, which allows you to create and manipulate a curved reformation, a Profile,
or an X-Section.
