ABSTRACT
Volume imaging vs. sections The study of three-dimensional structures of solid objects can utilize two-dimensional (2-D) or three-dimensional (3-D) imaging. Many of the 2-D images used in the preceding chapters have been sections through 3-D structures. This is especially true in the various types of microscopy, where either polished flat planes or cut thin sections are needed to form the images in the first place. But the specimens thus sampled are three-dimensional, and the goal of the microscopist is to understand the 3-D structure.
