Displaying images using the triplanar-dual view
The image window for the triplanar-dual view is quite similar to the image window for the triplanar view. The File and Options menus contain the same commands except for one command-the Options menu for the triplanar view contains the command Link to Another TriImage. Since the triplanar-dual view shows two datasets in the image window and allows you to manipulate them together, linking to another image is not necessary. Most of the icons and buttons on the toolbars for both views are the same with one primary difference: The triplanar-dual view allows you to create VOIs on the images; the triplanar view does not.
Like the triplanar view, you can use the icons and buttons on the toolbar to change magnification, draw, change colors, change opacity, and apply a new intensity to selected voxels in the images.
Showing and hiding axes, cross hairs, and Talairach grid
To display the axes on the images again, simply select Options > Show Axes. The check mark reappears in the check box in front of the command.
Creating VOIs on images
Note: You can only create one line VOI per orthogonal plane, although you can create a line VOI in each one of the three orthogonal planes.
Aligning the datasets
Finding the center of image datasets
Erasing part or all of drawings
File:MIPAV VisualizationTools189.gif
Caution: Make sure that you want to erase a part of the drawing or the entire drawing. There is no undo.
Cropping images
Note: The size of the box changes proportionally on all of the images shown in the triplanar-dual view.

Two small windows-one displaying the cropped area of Image A and the other displaying the cropped area of Image B-appear.

After you generate the cropped images, you can run algorithms on the images, apply a quick LUT on the images, or use any other image processing that's available in the MIPAV window on them.
Magnifying or minifying images
For information on how to use these icons, refer to "magnify or reduce a region of the image. You can magnify images to 32 times their original size, reduce them to one-fourth their original size, or restore them to their original size.".
Drawing on images
For example, if you highlight a particular area in the image in the triplanar-dual view, the same change is made on all of the images in the triplanar-dual view, but also on the images in the default view.
Painting an area on images in the triplanar-dual view affects images in the default image view

Opacity
|
Indicates the opacity of the paint. The further right you move the slider, the more opaque the paint color. The further left you move the slider, the more transparent the paint color.
