Display of Orthogonal Views

When a 3-dimensional image is loaded into Jim, you can display 2 views orthogonal to the regular imaging plane. For example, if you load a scan that shows axial sections, you can also show a coronal and a sagittal section through the data-set. As you click on the image, the location of these orthogonal views changes to follow the location of the mouse click.

Display orthogonal view from the View menu: .

This brings up the Orthogonal Views dialog:

If you do not see any orthogonal views in the dialog, then double click on the main displayed image to select a slice.

When you have a slice selected, you will see the yellow cross-hairs on the main image, and on the orthogonal views. These yellow lines show the location of the slices shown in each of the orthogonal views. Click anywhere on the displayed sections to move the location of the orthogonal views. If you click on the images in the Orthogonal Views Dialog, the selected slice will change as the slice position changes in response to your mouse clicks.

The orthogonal views are displayed in accordance with standard radiological convention; however, in order to do this, Jim needs to know the orientation of the image in the main display. If Jim is not able to determine this automatically, you may set the correct orientation by clicking on the correct button in the Orthogonal Views Dialog:

If the slice ordering does not follow the standard radiological convention (slice number increasing from inferior to superior, from right to left, and from anterior to posterior), then click the check box to tell Jim that the slice ordering is non-standard.

You can display the orthogonal sections with bi-linear interpolation by clicking the check box; this is particularly useful when the resolution in the slice direction is lower than the in-plane resolution.

The location of the orthogonal sections is shown in the readout at the bottom of the Orthogonal Views Dialog, either in pixels or mm, depending on the setting of the units button. When you have finished with the orthogonal views, click on the button.
