A new “lightbox image” output type has been added in latest Slicer Preview Release. In this mode captured images are exported as a large grid of images:
Images can be exported from any views, with any animation mode, just select “Output type” → “lightbox image”. Number of columns is adjustable in Advanced section.
Yes, you can choose any ROI: you set the first and last slice in the module and zoom in/out the view to select the relevant part within the slice. An alternative ia tonuae Crop Volume module before capturing the screenshots.
Note that all these are just for producing visuals for presentations, papers, etc. If you need to extract slices for data processing (preserving the data in full fidelity) then you can simply crop and resample the volume.
Understood, this is exactly why I need it. Apart from choosing the first and last slide and the number of images, is there a way to define the step and thickness of each slice? For example, an image taken every 1mm of the volume with 1mm thickness?
