After images have been loaded, the user can switch to the parallel image viewing page by selecting the Compare tab. PVIEW now shows three horizontal image display layouts. There are two display modes available, regular image display, and image fusion.
Regular Image Display Mode
The example below illustrates the regular image display mode, whereby each of the studies may have an independent layout. Note the Synchronize (for Synchronize compare display 1,2,3) and Color boxes highlighted in red. If they are checked, PVIEW switches all three rows to the same layout and synchronizes the images shown. This will only be successful for studies which have the origin at the same location and which cover the same image volume (the pixel size, however, might differ as in the case of a PET/CT study with the same reconstructed field-of-view).
Image Fusion Display Mode
In the fusion display mode the studies in the upper two rows are synchronized, while the third row shows the fusion image. As for synchronized image comparison, the studies must have the origin at the same location and cover the same image volume. A PET/CT example is shown below.
In the fusion mode all fusion renderings are available to prepare a meaningful fusion image. Additionally, by activating the Fusion tab it is possible to bring up a larger display of the active fusion image.
Switching the Display Mode
The display modes can be switched using the button close to the right lower corner, which changes according to the situation.
