The Navigation operator is selected by default when VivoQuant is opened. This tool enables the user to manually scroll through the image slices and rotate the Maximum intensity Projection (MIP). Similar functionality is available via the View Control tool.
To enter the Navigation Panel, select Navigation from the pull-down menu on the VivoQuant front panel.
There are several methods for operating the slice control navigator. This section describes manual manipulation using a mouse device. The View Control tool offers a wider array of options for controlling the Navigator window.
Navigation through the viewports includes scrolling through slices, zooming and panning.
To scroll through the individual slices, left click and move the mouse cursor up and down or to the side on the different viewports (sagittal, coronal or transverse).
To zoom in or out within a viewport, hold the
Shift key and move the mouse wheel forward or backward, respectively. Zooming is independent across viewports: zooming in one viewport will not affect the others, and all viewports may be zoomed to different amounts.
To pan within a viewport, hold the
Shift key and click and drag the mouse. Panning is independent across viewports: panning in one viewport will not affect the others, and all viewports may panned to different amounts.
At any time, the zooming and panning within viewports may be reset to their default positions by clicking the icon located on the toolbar.
The functions for controlling the MIP are slightly different than the functions that control the slices.
To freely rotate the VTK MIP, click and drag the mouse across the MIP. To zoom in and out, scroll the mouse wheel forward and backward. To pan around the MIP, hold the
Shift key and drag the mouse across the MIP. To rotate the MIP about a fixed axis of rotation, hold the
Ctrl key and drag the mouse in a circular motion across the MIP.
This information is also found in the MIP Control tool. For more information on using this tool, see the MIP Control page.
The tooltip feature is available by briefly holding a mouse left click on any of the three slice views (transverse, sagittal, coronal) in the Navigator window. The tooltip feature displays (x,y,z) coordinate locations and voxel values for each displayed data set for that (x,y,z) position.
