The purpose of the image fusion tool is to superimpose two DICOM series with the same spatial information on one another, so users can review images from both series simultaneously in a superimposed fashion.
The tool supports any two image sets which are (a) in the same study; (b) with the same number of images; and (c) have the same spatial information.
The tool button on the toolbar appears as below, a split button with a menu.
When the viewport selected has an image set which can be fused with another set in the same study according to image count and spatial data criteria, this button will be enabled:
Otherwise, it will be disabled.
In the menu, the menu items below (underlined in red) reflect image sets which can be fused with the image set in the viewport selected.
For instance, there are two eligible image sets for the following case.
If the users wishes to fuse series 8 with the current viewport, the user first selects the series in the button menu, then clicks the fusion tool button. The selected series will be laid over the current viewport, and will use a color scheme from the available palettes listed in the menu.
For example, a single series viewport such as the below:
may appear as follows when fused with a second series:
The hot palette was used as the color map for the foreground image set.
Users may assign to the window/level tool either the function of windowing and levelling the image, or adjusting the opacity of the overlay, as follows:
