Abstract: Image analysis systems components, devices, and methods are provided for viewing the image data stack in less time with less effort and less repetitive motions. The navigation device, for example, can include: (i) an indexing state selector for independently selecting a desired subset within the independently viewable subsets, the desired subset indexed for an efficient image selection with a single click of the indexing state selector; and, (ii) a scrolling state selector for scrolling through the desired subsest as a data series of the discrete images. And, a graphical user interface can be operably connected to the processor for viewing the plurality of sets of discrete sets of images. The systems, components, devices, and methods provided are solutions to the problem of providing rapid, efficient process for viewing a data-stack of images by implementing, for example, “point-free” steps and less repetitive motions.
