Whole slide imaging and multiplexing provide rich data extraction and depth of detail while keeping the whole specimen in the field of view.BRENDAN BRINKMAN, OLYMPUS CORP.Whole slide imaging is a method principally employed when scientists need to image a large, relatively two-dimensional sample that expands beyond a single microscope field of view. Typical applications include imaging of histological tissues that have been cut into thin slices and placed on a glass slide.
