Working in Fusion Mode

Multiple datasets can be combined in the same scene to compare images of an object recorded at different times or with different imaging modalities. This fusion of image data can increase the amount of information and accuracy in models.

Dragonfly provides automatic rigid registration and also allows for manual registration through interactive manipulators to register datasets in a fused view (see Registering Datasets).

Artifacts may be introduced by poor alignment of structures between the image layers in the fused view. You should check registration accuracy prior to image interpretation and adjust the transparency of the layers appropriately.

Fused CT/PET view

Fused views can be created by simply changing the visibility of your image data in the Data Properties and Settings panel.

Data Properties and Settings panel

You can change the opacity of images within a fused view, as well as apply color ramps, to improve the visualization of fused images.

The arrangement of objects in the Data Properties and Settings list determines the order of visibility in a view. Objects at the top of the list are displayed over objects that are lower down (see Object List for more information).
