Merge Slices & Stitching

The Merge Slices & Stitching tool allows combining in the axial direction the selected studies to form a static series with extended coverage.

Activating Merge Slices & Stitching opens a dialog window as illustrated below:


The list in the upper left shows the loaded image series in loading order. The list in the upper right shows the image series which will be combined into a static series with the current sorting order. Initially, all series appear in the original order.

Merging List Preparation

Series can be copied from left to right by double clicking in the left list, or selecting a list element and activating the arrow between the lists. The double arrow copies all loaded series to the right.

The order of the Merge list can be modified by selecting a list element and shifting its position by the arrows to  the right.


If the columns contain information which is suitable for sorting, the sorting button AZ can be enabled and sorting started by clicking into the column header.

There are two options available for simple merging: Merge one single frame study and Merge frame by frame.

This function is only reasonable for image series covering adjacent axial fields-of-view such as in whole-body scanning.

Note that at least two studies have to be selected for merging.

Stitch by Origins

The procedure assumes the images have the same spatial frame of reference and merges them based on slices position. The first image in the merging list is set as reference.


The interface is organized in 3 main areas:

1.Fusion controls and source settings on the right hand side

2.Fusion display of the source images in the central viewport

3.Settings for the stitching procedure and the preview of the results on the right hand side.

CoRegister and Stitch

The procedure can be applied for two images. It consists in a matching step followed by the merging step.  Two types of matching are supported: the manual matching and the rigid matching procedure. Fore detail information about the matching procedures please refer to the Fusion guide.
