X-ray Microscopic Inspection of Concrete

Figure 1: Clipped 3D Volumetric rendering of concrete sample While the words concrete and cement are often used interchangeably in everyday conversation, concrete is actually a mixture of aggregate material (rocks, other filler) and cement. X-ray microscopy permits non-destructive examination of geological samples and construction materials, such as cement and concrete, for …

Micro-CT Applications for Digitizing Biological Specimens

(Above:) A neuropteran insect (genus Sisyra) showing musculature and general soft tissue morphology. Fixed in Bouin’s fluid and stained with I2E, scanned in ethanol. Virtual horizontal sections one voxel thick (top), and cutaway volume renderings (bottom). Muscles are especially clearly defined, and the complete penetration of iodine makes it more suitable than …

X-ray Microscopic Inspection of Insect Flight Muscles

Micro-CT imaging allows researchers to visualize both the internal and external features of an object without destroying the specimen, which makes this technique ideal for digitizing chemically-dried insect specimens. With micro-CT, valuable natural history collections can now be digitized while preserving the original objects. Micro-CT allows for high resolution examination of insect …

Micro-CT Examination of a Tree Mushroom

Polypores are a group of fleshy fungi with pores or tubes underneath. Taxonomically, the polypores are complicated and not completely understood, with an amazing amount of morphological diversity. While many can be identified by their macro features and the host tree they are attached to, if a mushroom grows on a large …

Micro-CT Examination of Sardines Packed in Oil

The food processing and manufacturing industry utilizes micro-CT analysis in several ways, from studying the distribution of ingredients within products to inspecting finished packaging for foreign materials and checking product distribution within the packaging. Further, micro-CT allows researchers to study intact internal microstructure data non-invasively, as we were able to demonstrate with …

Micro-CT for Primate Studies

Micro-CT examination of the primate cranial morphospace allows scientists to explore developmental, evolutionary, and functional influences that have contributed to primate cranial diversity. The primate cranium is quite complex, supporting vital functions such as respiration, olfaction, food acquisition and mastication, communication, and protection of the brain and eyes. Natural selection within different …

Micro-CT Examination of Additively Manufactured Parts

Micro-CT has become widely used to analyze and test additively manufactured parts, particularly for porosity analysis and dimensional measurement. In conventional manufacturing, a weld would always be inspected for voids and inclusions, but in additive manufacturing the entire sample is essentially one large weld. Therefore, to qualify and verify safety-critical aerospace, automotive, …
