In a CT system, X-ray photons emitted from an X-ray tube will travel through the object and hit a detector. The detector senses the dose at each pixel of the detector area. This creates digital images while the object is rotated. The reconstruction software calculates virtual slices based on the dose at each location from different angles. The result is called a tomogram. Each pixel in the tomogram represents a density of material, a voxel.

There is a range of terminology for CT system accuracy and uncertainty that should be understood when evaluating 3D scanning systems, this blog post illustrates some of those terms, such as Precision and Accuracy, Tolerance, Uncertainty of Measurement, Resolution, Error, and Suitability.

Starting out mainly as a prototyping technology Additive Manufacturing (AM) gained tremendous momentum for  use in industrial applications over the last 5 years. For highly demanding functional parts, laser beam powder bed fusion (LB-PBF) became the most dominant AM technology.

The Zoological Museum in the Center for Natural History at the University of Hamburg is currently running a special exhibition about the tragic phenomenon of disappearing species in the animal kingdom.
