Azimuthal X-ray scattering patterns from a bamboo sample. The spatially-localized X-ray scattering intensities from an outer culm wall bamboo sample shows tissue-specific scattering patterns originating mostly from fibers (1, 2, 3) and from parenchyma only (4). The rectangles on the top of the tomographic reconstruction slice (left, scale bar \(400\,\mu \hbox {m}\)) show the approximate X-ray beam paths for the measurements corresponding to the azimuthal intensity profiles on the right. The scale bar is \(400\,\mu \hbox {m}\) and the profiles are shifted vertically for clarity
