The Status section displays the image size, which is the number of voxels in the X-, Y-, and Z-directions, as well as the voxel length.

The Dataset pull-down menu contains the current processed image and the previous step. Selecting an image from this menu loads it in the Image Processing dialog.

Additionally, you can load different image datasets in the Image Processing dialog while keeping the Keep existing Volume Fields option selected in the Import Geometry dialog. It is easy to switch between several images that are loaded simultaneously.
