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.
File
|
Close Frame-Closes this window.
| ||
Options
|
Show Axes-Displays the XY (top left), ZY (top right), and ZX (bottom left) axes on the images.
| ||
Show Cross Hairs-Displays the cross-hair lines on the images. When you move these lines on one image, it also moves to the corresponding points all of the other images.
| |||
Show Talairach Grid-Displays a Talairach (stereo tactic) grid on the images.
| |||
Aligns two images.
| |||
Enlarges the images to twice their current size. It might be necessary to manually resize the window and use scroll bars to view all of the images.
| |||
Reduces the images to half of their current size.
| |||
Restores the images to their original size.
| |||
Draw a line VOI.
| |||
Reassigns a new center to each dataset. The location that you select appears in the center of each image.
| |||
Allows you to apply a transformation matrix to an image dataset.
| |||
Applies the rotations and translations made to the images.
| |||
Draws a point on an image. This point is only on the image you select.
| |||
Indicates that the next VOI is a new VOI rather than a change to the currently existing VOI.
| |||
Removes the point VOI from the image.
| |||
Displays the bounding box, which is outlined in red, on each image.
| |||
Displays in a separate image window only the area enclosed by the bounding box. When you click this icon, the Crop Image dialog box opens. {| align="center" |
